Overview
The LM324DTBR2 is a part of the LM324 series, which are low-cost, quad operational amplifiers with true differential inputs. These amplifiers are designed for single supply operations and offer several distinct advantages over standard operational amplifier types. They 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 suitable for a wide range of applications.
