Description:
The Microchip Technology Inc. MCP651/1S/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 (MCP651 and
MCP651S), single with CAL/CS pin (MCP653), 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.

Note 1: The MCP652 single, MCP653 single, MCP655 dual and MCP659 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 MCP655 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 tog-
gled 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 MCP659 quad, there is an additional constraint. CALAD/CSAD and CALBC/CSBC can be toggled simultane-
ously (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.
