Overview
The LM324ADG, 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. The LM324ADG can operate at supply voltages ranging from 3.0 V to 32 V, with quiescent currents significantly lower than those of the MC1741. This makes them highly efficient and versatile for various electronic circuits.
