Overview
The LM324ANG is a part of the LM324 series, which are low-cost, quad operational amplifiers produced by ON Semiconductor. These amplifiers are known for their true differential inputs and several distinct 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 other operational amplifiers like the MC1741. The LM324ANG is suitable for a wide range of applications due to its versatility and low power consumption.
