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.
