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.
