The MCP604-I/ST is a low-power Operational Amplifier is offered in quad (MCP604) configurations. The op amp utilize an advanced CMOS technology that provides low bias current, high speed operation, high open-loop gain and rail-to-rail output swing. Product offering operates with a single supply voltage that can be as low as 2.7V, while drawing 230μA (typical) of quiescent current per amplifier. In addition, the common mode input voltage range goes 0.3V below ground, making these amplifiers ideal for single-supply operation. Device is appropriate for low power, battery operated circuits due to the low quiescent current, for A/D convert driver amplifiers because of their wide bandwidth or for anti-aliasing filters by virtue of their low input bias current.
