LM392DR

Texas Instruments · Special Purpose Amplifiers · SOIC-8

LM392DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTPUT A (Comparator) output Comparator A output is compatible with all types of logic systems, with low saturation voltage of 250 mV at 4 mA and direct interface to TTL or CMOS logic.
2 INVERTING INPUT A input Inverting input of comparator A; the input voltage must not go below -0.3 V and either input can go to 32 V without damage.
3 NONINVERTING INPUT A input Noninverting input of comparator A; the input voltage must not go below -0.3 V and the common-mode input range includes ground.
4 GND power_in Ground reference pin; the input common-mode range includes ground, allowing sensing at or near ground.
5 NONINVERTING INPUT B input Noninverting input of the operational amplifier B; the common-mode range is 0 V to V+ - 1.5 V and the input must not go below -0.3 V.
6 INVERTING INPUT B input Inverting input of the operational amplifier B; the common-mode range is 0 V to V+ - 1.5 V and the input must not go below -0.3 V.
7 OUTPUT B (Operational Amplifier) output Operational amplifier B output swings from 0 V to V+ - 1.5 V with a 2 kΩ load, and a short to ground is limited to approximately 40 mA.
8 V+ power_in Positive supply: 3 V to 32 V single supply, or ±1.5 V to ±16 V dual supply.
