Texas Instruments LM392 Low-Power Operational Amplifier and Voltage Comparator LM392DRG4

The LM392DRG4 is a low-power operational amplifier and voltage comparator from Texas Instruments, designed to operate from a single power supply ranging from 3V to 32V or dual supplies of ±1.5V to ±16V. It features a low input bias current of 50 nA and a low input offset voltage of 2 mV, making it suitable for precision applications. The device is internally frequency compensated for unity gain and offers a large DC voltage gain of 100 dB with a bandwidth of 1 MHz. The output voltage swing is from 0V to V+ - 1.5V, and it can drive loads with a low output saturation voltage of 250 mV at 4 mA. The LM392DRG4 is particularly useful in battery-powered devices due to its low supply current and ability to eliminate the need for dual power supplies. Applications include transducer amplifiers, DC gain blocks, and voltage comparators interfacing with TTL or CMOS logic systems.
