This technical brief introduces Microchip’s cascaded dual op amps: MCP627X (2 MHz), MCP628X (5 MHz) and MCP629X (10 MHz). Features of this new topology include a Chip Select (CS) pin for both amplifiers, small 8-pin packages (PDIP-8, SOIC-8, MSOP-8), and a pinout similar to the industry standard for duals. The two op amps are connected so as to support many application circuits.
