The MCP604 quad operational amplifier (op amp) has a gain bandwidth product of 2.8 MHz with low typical operating current of 230 uA. The MCP604 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 MCP604 operates with a single supply voltage that can be as low as 2.7V, while drawing less than 325 uA of quiescent current per amplifier. The MCP604 is available in standard 14-lead PDIP, SOIC and TSSOP packages. This amplifier is ideal for industrial process control, low-power battery-operated devices, portable equipment, data acquisition equipment, test equipment and low-end audio applications.
