Design Aids:
The Microchip Technology Inc. MCP631/2/3/4/5/9
family of operational amplifiers features high gain
bandwidth product (24 MHz, typical) and high output
short-circuit current (70 mA, typical). Some also
provide a Chip Select (CS) pin that supports a
low-power mode of operation. 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 (MCP631), single with
CS pin (MCP633), dual (MCP632), dual with two CS
pins (MCP635), quad (MCP634) and quad with two
Chip Select pins (MCP639). All devices are fully
specified from -40°C to +125°C.
