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.
