Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. 1 • • • • • • • • • • • Wide Supply – Voltage Range: 2.0 V to 36 V – Single or Dual Supplies: ±1.0 V to ±18 V Very Low Supply Current Drain (0.4 mA) — Independent of Supply Voltage Low Input Biasing Current: 25 nA Low Input Offset Current: ±5 nA Maximum Offset voltage: ±3 mV Input Common-Mode Voltage Range Includes Ground Differential Input Voltage Range Equal to the Power Supply Voltage Low Output Saturation Voltage: 250 mV at 4 mA Output Voltage Compatible with TTL, DTL, ECL, MOS and CMOS logic systems Available in the 8-Bump (12 mil) DSBGA Package See AN-1112 (SNVA009) for DSBGA Considerations Advantages – High Precision Comparators – Reduced VOS Drift Over Temperature – Eliminates Need for Dual Supplies – Allows Sensing Near Ground – Compatible with All Forms of Logic – Power Drain Suitable for Battery Operation 2 Applications • • Battery powered applications Industrial applications Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM193-N series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM19-N series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.

If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than −0.3V (or 0.3V below the magnitude of the negative power supply, if used). This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than −0.3V. For operating at high temperatures, the LM393 and LM2903 must be derated based on a 125°C maximum junction temperature and a thermal resistance of 170°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM193/LM193A/LM293 must be derated based on a 150°C maximum junction temperature. The low bias dissipation and the “ON-OFF” characteristic of the outputs keeps the chip dissipation very small (PD≤100 mW), provided the output transistors are allowed to saturate. Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output current is approximately 20 mA independent of the magnitude of V+. 7.2 ESD Ratings V(ESD) (1) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) VALUE UNIT ±1300 V JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. 7.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN Supply Voltage (V+) - Single Supply 2.0 NOM MAX UNIT 36 V ±1.0 ±18 V 0 (V+) -1.5V V Operating junction temperature, TJ : LM193/LM193A -55 125 °C Operating junction temperature, TJ : LM2903 -40 85 °C Operating junction temperature, TJ : LM293 -25 85 °C Operating junction temperature, TJ : LM393 0 70 °C Supply Voltage (V+) - Dual Supply Operating Input Voltage on (VIN pin) 4 Submit Documentation Feedback Copyright © 1999–2014, Texas Instruments Incorporated Product Folder Links: LM193-N LM2903-N LM293-N LM393-N LM193-N, LM2903-N, LM293-N, LM393-N www.ti.com SNOSBJ6F – OCTOBER 1999 – REVISED DECEMBER 2014 7.4 Thermal Information LMx93 THERMAL METRIC (1) TO-99 UNIT 8 PINS RθJA (1) Junction-to-ambient thermal resistance 170 °C/W For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 7.5 Electrical Characteristics: LM193A V+= 5 V, TA = 25°C Unless otherwise stated.

The low power consumption of 0.4mA at 5V and the 2.0V supply operation makes the LM139 suitable for battery powered applications. 8.2 Functional Block Diagram Figure 11. Basic Comparator 8.3 Feature Description The input bias current of 25 nA enables the LM193 to use even very high impedance nodes as inputs. The differential voltage input range equals the supply voltage range. The LM193 can be operated with a single supply, where V+ can be from 2.0 V to 36 V, or in a dual supply voltage configuration, where GND pin is used as a V– supply. The supply current draws only 0.4 mA for both comparators. The output of each comparator in the LM193 is the open collector of a grounded-emitter NPN output transistor which can typically draw up to 16mA. 8.4 Device Functional Modes A basic comparator circuit is used for converting analog signals to a digital output. The output is HIGH when the voltage on the non-inverting (+IN) input is greater than the inverting (-IN) input. The output is LOW when the voltage on the non-inverting (+IN) input is less than the inverting (-IN) input. The inverting input (-IN) is also commonly referred to as the "reference" or "VREF" input. All pins of any unused comparators should be tied to the negative supply. 10 Submit Documentation Feedback Copyright © 1999–2014, Texas Instruments Incorporated Product Folder Links: LM193-N LM2903-N LM293-N LM393-N LM193-N, LM2903-N, LM293-N, LM393-N www.ti.com SNOSBJ6F – OCTOBER 1999 – REVISED DECEMBER 2014 9 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The LM193 series are high gain, wide bandwidth devices which, like most comparators, can easily oscillate if the output lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance. This shows up only during the output voltage transition intervals as the comparator change states. Power supply bypassing is not required to solve this problem. Standard PC board layout is helpful as it reduces stray input-output coupling. Reducing the input resistors to < 10 kΩ reduces the feedback signal levels and finally, adding even a small amount (1.0 to 10 mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback are not possible. Simply socketing the IC and attaching resistors to the pins will cause inputoutput oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relatively fast rise and fall times, hysteresis is not required. All input pins of any unused comparators should be tied to the negative supply. The bias network of the LM193 series establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 2.0 VDC to 30 VDC. The differential input voltage may be larger than V+ without damaging the deviceTypical Applications . Protection should be provided to prevent the input voltages from going negative more than −0.3 VDC (at 25°C). An input clamp diode can be used as shown in Typical Applications . The output of the LM193 series is the uncommitted collector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output OR'ing function. An output pullup resistor can be connected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage which is applied to the V+ terminal of the LM193 package. The output can also be used as a simple SPST switch to ground (when a pullup resistor is not used). The amount of current which the output device can sink is limited by the drive available (which is independent of V+) and the β of this device. When the maximum current limit is reached (approximately 16mA), the output transistor will come out of saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the approximately 60Ω rSAT of the output transistor. The low offset voltage of the output transistor (1.0mV) allows the output to clamp essentially to ground level for small load currents. 9.2 Typical Applications 9.2.1 Basic Comparator Figure 12. Basic Comparator 9.2.1.1 Design Requirements The basic usage of a comparator is to indicate when a specific analog signal has exceeded some predefined threshold. In this application, the negative input (IN–) is tied to a reference voltage, and the positive input (IN+) is connected to the input signal. The output is pulled up with a resistor to the logic supply voltage, V+ with a pullup resistor. For an example application, the supply voltage is 5V. The input signal varies between 1 V and 3 V, and we want to know when the input exceeds 2.5 V±1%. The supply current draw should not exceed 1 mA.

With the 5-V supply voltage, we would use a voltage divider consisting of one resistor from the supply to IN- and an second resistor from IN–. The 25 nA of input current bias should be < 1% of the bias current for Vref. With a 100-kΩ resistor from IN– to V+ and an additional 100-KΩ resistor from IN– to ground, there would be 25 µA of current through the two resistors. The 3-kΩ pullup shown will need 5 V/3 kΩ → 1.67 mA, which exceeds our current budget. With the 400-µA supply current and 25 µA of VREF bias current, there is 575 µA remaining for output pullup resistor; with 5-V supply, we need a pullup larger than 8.7 kΩ. A 10-kΩ pullup is a value that is commonly available and can be used here. 9.2.1.3 Application Curve Figure 13.

For this reason, bypassing the power supply with 1.0μF to ground will provide improved performance; the supply bypass capacitor should be placed as close as possible to the supply pin and have a solid connection to ground. The bypass capacitor should have a low ESR and also a SRF greater than 50MHz. 11 Layout 11.1 Layout Guidelines Try to minimize parasitic impedances on the inputs to avoid oscillation. Any positive feedback used as hysteresis should place the feedback components as close as possible to the input pins. Care should be taken to ensure that the output pins do not couple to the inputs. This can occur through capacitive coupling if the traces are too close and lead to oscillations on the output. The optimum placement for the bypass capacitor is closest to the V+ and ground pins. Take care to minimize the loop area formed by the bypass capacitor connection between V+ and ground. The ground pin should be connected to the PCB ground plane at the pin of the device. The feedback components should be placed as close to the device as possible minimizing strays. 11.2 Layout Example Figure 38.
