The MCP606/7/8/9 family of operational amplifiers (op amps) from Microchip Technology Inc. are unity-gain stable with low offset voltage (250 µV, max.). Performance characteristics include rail-to-rail output swing capability and low input bias current (80 pA at +85°C, max.). These features make this family of op amps well suited for single-supply, precision, high impedance, battery-powered applications.
