MCP608

The MCP608 operational amplifier (op amp) has a gain bandwidth product of 155 kHz with a low typical operating current of 18.7 and an offset voltage that is less than 250 µV. The MCP608 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 MCP608 features a single amplifier with chip select and operates as low as 2.5V, while drawing less than 25 of quiescent current. The MCP608 is available in standard 8-lead PDIP, SOIC and TSSOP 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. AEC-Q100 Grade 1 qualification is available for this device
