The Microchip Technology, Inc. MCP651/2/5 family of operational amplifiers features low offset. At power up, these op amps are self-calibrated using mCal. Some package options also provide a calibration/chip select pin (CAL/CS) that supports a low power mode of operation, with offset calibration at the time normal operation is re-started. These amplifiers are optimized for high speed, low noise and distortion, single-supply operation with rail-to-rail output and an input that includes the negative rail.
