Overview
The LM224NG, manufactured by onsemi, is a low-cost, quad operational amplifier (op-amp) designed for a wide range of electronic applications. This device features true differential inputs and is particularly advantageous in single supply applications. The LM224NG can operate at supply voltages ranging from 3.0 V to 32 V, making it versatile for various circuit designs. It is known for its low quiescent currents, which are about one-fifth of those associated with the MC1741 on a per amplifier basis. The common mode input range includes the negative supply, eliminating the need for external biasing components in many applications.
