LM3403 Quad Operational Amplifier 3V 2.8mA IC DIP-14

Description

LM3403 Quad Operational Amplifier 3V 2.8mA IC DIP-14 The LM3403 is a monolithic quad operational amplifier that integrates four independent high-gain operational amplifiers within a single package. Each amplifier is internally frequency compensated, simplifying circuit design while providing stable operation across a wide range of analog applications. The device is designed to operate from either a single supply or dual power supplies, making it suitable for both industrial and general-purpose electronic systems. A key advantage of the LM3403 is its input common-mode range, which includes the negative supply rail, allowing direct interfacing with ground-referenced signals without requiring additional biasing circuitry. The device features a Class-AB output stage for reduced crossover distortion and short-circuit protected outputs, making it useful in active filters, oscillators, instrumentation circuits, signal conditioning systems, and voltage reference applications. Features: Four independent operational amplifiers in one package. Internally frequency compensated for stable operation. Operates from single or dual power supplies. Input common-mode voltage range includes ground. Output voltage swing extends to ground. Class-AB output stage. High open-loop voltage gain. Short-circuit protected outputs Suitable for analog signal processing. Compatible with general-purpose op-amp applications. Low external component requirement. Good channel isolation between amplifiers.
