LM392M

The LM392M series from Texas Instruments integrates two independent building blocks: a high-gain, internally frequency-compensated operational amplifier and a precision voltage comparator. This dual functionality allows for versatile circuit design within a single package.

The operational amplifier offers a large DC voltage gain of 100 dB and a 1 MHz bandwidth at unity gain. Its output voltage swing can reach from 0V to V+ - 1.5V. The comparator section provides a low output saturation voltage of 250 mV at 4 mA and is compatible with all logic systems.

Designed for low power consumption, the LM392M draws only 600 μA of supply current, which is essentially independent of the supply voltage. It features low input biasing current of 50 nA, low input offset voltage of 2 mV, and low input offset current of 5 nA. The input common-mode voltage range includes ground, and the differential input voltage range is equal to the power supply voltage.

This component is supplied in an 8-pin SOIC (D) package, suitable for surface mounting. It operates within a temperature range of 0°C to 70°C. The pinout is compatible with industry-standard devices like the LM358 dual op amp and LM393 dual comparator, simplifying drop-in replacements.
