Overview
The LM224DTBG, manufactured by onsemi, is a low-cost, quad operational amplifier (op-amp) with true differential inputs. This device is part of the LM224 series, which offers several distinct advantages over standard operational amplifier types, particularly in single supply applications. The LM224 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, eliminating the need for external biasing components in many applications. The device is internally compensated and features short-circuited protected outputs, enhancing its reliability and ruggedness.
