MICROCHIP MCP601 CMOS Single Op-Amp, RRO, SOT23-5

The MICROCHIP MCP601T-I/OT is a low-power, single-supply CMOS operational amplifier designed for high-performance applications. Utilising advanced CMOS technology, it offers an excellent combination of low bias current, high-speed operation, high open-loop gain, and a rail-to-rail output swing. Its common mode input voltage range extends 0.3V below ground, making it perfectly suited for single-supply operation where maximum signal swing is required.

This device is ideal for power-sensitive designs, such as battery-operated circuits, due to its exceptionally low quiescent current. Its wide bandwidth makes it a superb choice for driving analogue-to-digital converters, while its low input bias current is beneficial for creating precision anti-aliasing filters. The amplifier is unity-gain stable, ensuring reliable performance in a wide variety of feedback configurations.
