MCP601 Single Operational Amplifier, 2.8MHz, SOIC-8

The MCP601-I/SN from MICROCHIP is a high-performance, low-power CMOS operational amplifier designed for single-supply applications. It utilises an advanced CMOS technology to deliver a compelling combination of low bias current, high-speed operation, high open-loop gain, and a rail-to-rail output swing. A key feature is its extended common-mode input voltage range, which includes ground and extends 0.3V below it, making this op-amp exceptionally well-suited for circuits operating from a single voltage source.

This device is engineered for efficiency, with a typical quiescent current of just 230µA, making it an ideal choice for battery-powered and portable electronics where conserving power is critical. Its wide 2.8MHz gain bandwidth product and fast 2.3V/µs slew rate ensure it can handle a variety of signal processing tasks with precision and speed. The amplifier is unity-gain stable, simplifying circuit design and enhancing reliability in feedback configurations.

Key Features & Specifications
