The MCP602 is a dual Operational Amplifier IC has a gain bandwidth product of 2.8MHz with low typical operating current of 230μA and an offset voltage that is less than 2mV. It uses Microchip's advanced CMOS technology, which provides low bias current, high-speed operation, high open-loop gain and rail-to-rail output swing. The MCP602 operates with a single supply voltage that can be as low as 2.7V, while drawing less than 325 of quiescent current per amplifier.
The device contains two independent op-amps in a single package, making it convenient for designs requiring multiple op-amps but wanting to save on board space and component count. Both the input and output voltage ranges can swing all the way from the negative supply voltage to the positive supply voltage, which is useful for single-supply applications, as well as for maximizing the output range.
