The MCP618 operational amplifier (op amp) has a gain bandwidth product of 190 kHz with a low typical operating current of 19 µA and an offset voltage that is less than 150 µV. The MCP618 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 MCP618 features a single amplifier with chip select and operates as low as 2.3V, while drawing less than 25 µA of quiescent current. The MCP618 is available in standard 8-lead PDIP, SOIC and MSOP packages. This amplifier is ideal for battery and loop-powered applications as well as industrial process control, low-power battery-operated devices, portable equipment, data acquisition equipment, test equipment and low-end audio applications.
