Description
The Microchip Technology, Inc. MCP621/2/5 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.
This family is offered in single with CAL/CS pin
(MCP621), dual (MCP622) and dual with CAL/CS pins
(MCP625). All devices are fully specified from -40°C to
+125°C.
