Overview
The LM324ADR2, part of the LM324 series, is a low-cost, quad operational amplifier produced by onsemi. These amplifiers are designed with true differential inputs and offer several advantages over standard operational amplifier types, particularly in single supply applications. They 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 includes the negative supply voltage, eliminating the need for external biasing components in many cases. The output voltage range also includes the negative power supply voltage, making them versatile for various applications.
