Description

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 V. 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.

The MCP606, MCP607, MCP608 and MCP609 from Microchip Technology, Inc. are unity gain stable, low offset voltage operational amplifiers capable of precision low power single supply operation. Performance characteristics include ultra low offset voltage (250V, max), rail-to-rail output swing capability, and low input bias current (80pA@85C). These features make this family of amplifiers well suited for single supply precision, high impedance, battery powered applications.

The single MCP606 is available in standard 8-lead PDIP, SOIC, and TSSOP packages. Another version of the single op amp, MCP608 is offered with a ChipSelect option in standard 8-lead PDIP, SOIC, and TSSOP packages. The dual MCP607 is offered in standard 8-lead PDIP, SOIC, as well as the TSSOP package. Finally, the quad MCP609 is offered in 14-lead PDIP, SOIC and TSSOP packages. All devices are fully specified from -40 °C to +85 °C with power supplies from 2.5V to 5.5V.
