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.

Note 1: The MCP622 single, MCP625 dual and MCP629 quad have their CAL/CS inputs internally pulled down to VSS (0V).
2: 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.
3: For the MCP625 dual, there is an additional constraint. CALA/CSA and CALB/CSB can be toggled simultaneously
(within a time much smaller than tCSU) to make both op amps perform the same function simultaneously. If they are
toggled independently, then CALA/CSA (CALB/CSB) cannot be allowed to toggle while op amp B (op amp A) is in
Calibration mode; allow more than the maximum tCON time (4 ms) before the other side is toggled.
4: For the MCP629 quad, there is an additional constraint. CALAD/CSAD and CALBC/CSBC can be toggled simultaneously
(within a time much smaller than tCSU) to make all four op amps perform the same function simultaneously, and the
maximum tCON time is approximately doubled (8 ms). If they are toggled independently, then CALAD/CSAD
(CALBC/CSBC) cannot be allowed to toggle while op amps B and C (op amps A and D) are in Calibration mode; allow
more than the maximum tCON time (8 ms) before the other side is toggled.
