Description
The Microchip Technology, Inc. MCP651/2/4/5/9 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
(MCP651), dual (MCP652), dual with CAL/CS pins
(MCP655), quad (MCP654) and quad with CAL/CS
pins (MCP659). All devices are fully specified from
-40°C to +125°C.

The MCP652 single, MCP655 dual and MCP659 quad have their CAL/CS inputs internally pulled down to V
SS
(0V).
This time ensures that the internal logic recognizes the edge. However, for the rising edge case, if CAL/CS is raised
before the calibration is complete, the calibration will be aborted and the part will return to low power mode.
For the MCP655 dual, there is an additional constraint. CAL
A
/CS
A
and CAL

(within a time much smaller than t
