Description
The Microchip Technology Inc. MCP621/1S/2/3/4/5/9 family of high bandwidth and high slew rate 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.
This family is offered in single (MCP621 and MCP621S), single with CAL/CS pin (MCP623), dual (MCP622), dual with CAL/CS pins (MCP625), quad (MCP624) and quad with CAL/CS pins (MCP629). All devices are fully specified from -40°C to +125°C.
