MCP6051/2/4 family of operational amplifiers (op amps) has low input offset voltage (±150 ìV, maximum) and rail-to-rail input and output operation. This family is unity gain stable and has a gain bandwidth product of 385 kHz (typical). These devices operate with a single supply voltage as low as 1.8V, while drawing low quiescent current per amplifier (30 ìA, typical). These features make the family of op amps well suited for single-supply, high precision, battery-powered applications. The MCP6051/2/4 family is offered in single (MCP6051), dual (MCP6052), and quad (MCP6054) configurations. The MCP6051/2/4 is designed with Microchip’s advanced CMOS process. All devices are available in the extended temperature range, with a power supply range of 1.8V to 6.0V.

This circuit can independently set VCM and VOUT; see Equation 1-1. Note that VCM is not the circuit’s common mode voltage ((VP + VM)/2), and that VOST includes VOS plus the effects (on the input offset error, VOST) of temperature, CMRR, PSRR and AOL.
