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.
