LM3900 amplifier
This content will be shared across all product pages.
Description:
The LM3900 is a quad operational amplifier (op-amp) with a unique design that allows single-supply operation. Unlike traditional op-amps, the LM3900 can operate with input and output voltages very close to the ground or zero voltage, making it ideal for low-voltage and single-supply applications. Each of the four op-amps in the LM3900 is designed to be used independently, providing versatility in various analog signal processing tasks.
