MC3403 Quad Low Power Operational Amplifier (DIP-14)

The MC3403 is a versatile quad operational amplifier designed to provide high performance in both single and dual power supply applications. Unlike the standard 324 series, the MC3403 utilizes a Class AB output stage, which significantly reduces crossover distortion and makes it better suited for high-quality audio and precision analog signal processing. Each of the four amplifiers is internally frequency compensated, ensuring stable operation across a wide range of gains. Its ability to sense signals near ground while operating from a single supply makes it an ideal choice for battery-powered instruments and automotive sensors. Housed in a standard 14-pin dual in-line package (DIP-14), it is commonly used in active filters, DC gain blocks, and traditional op-amp circuits where space efficiency and low power consumption are required.
