LMC660 CMOS Quad Operational Amplifier IC SMD Package

Each amplifier in the LMC660 family operates with rail-to-rail input and output, allowing the output voltage to swing nearly to both supply rails, maximizing dynamic range. The input bias current is in the femtoampere range (fA), ensuring negligible loading on high-impedance sources such as sensors, photodiodes, and transducers.

The device supports both single-supply (3V to 15V) and dual-supply (±1.5V to ±7.5V) operation, providing design flexibility for low-voltage or standard analog systems. The amplifiers feature unity-gain stability, enabling use in voltage followers, filters, and amplifiers without additional compensation.

Due to its low input offset voltage, low power dissipation, and wide bandwidth, the LMC660 is an excellent choice for portable, precision, and industrial-grade analog applications.
