MCP6271/1R/2/3/4/5 family of operational amplifiers (op amps) provide wide bandwidth for the current. This family has a 2 MHz 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 170 µA (typical) quiescent current. The MCP6271/1R/2/3/4/5 supports rail-to-rail input and output swing, with a Commonmode input voltage range of VDD + 300 mV to VSS – 300 mV. This family of op amps is designed with Microchip’s advanced CMOS process. The MCP6275 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 op amp B). The CS input puts the device in low power m...
