The MCP6273-E/P is a rail-to-rail Operational Amplifier provide wide bandwidth for the current. This family has a 2MHz gain bandwidth product (GBWP) and a 65° phase margin. This family also operates from a single supply voltage as low as 2.0V, while drawing 170μA (typical) quiescent current. This supports rail-to-rail input and output swing, with a common mode input voltage range of VDD + 300mV to VSS-300mV. This family of operational amplifier is designed with Microchips advanced CMOS process. This has a Chip Select input (CS) for dual op amps in an 8-pin package and is manufactured by cascading two op amps (the output of op amp A connected to the non-inverting input of operational amplifier B). The CS input puts the device in low power mode.
