Overview
The LM2904ADMR2G is a single supply dual operational amplifier produced by onsemi. This device leverages the circuit designs developed for quad operational amplifiers, offering low power consumption and the ability to operate with either single or split supply configurations. The LM2904 series is equivalent to one-half of the LM324, providing several advantages over standard operational amplifiers in single supply applications. It can operate at supply voltages ranging from 3.0 V to 32 V, with quiescent currents significantly lower than those of the MC1741. The common mode input range extends to the negative supply, eliminating the need for external biasing components in many applications.
