Micropower BiCMOS op-amps

20 June 2001 Analogue, Mixed Signal, LSI

Microchip's MCP61X family are unity gain stable op-amps with low offset voltage. These single supply op-amps offer a gain bandwidth of 190 kHz with an operating current of 20 µA. They also have low offset voltage and voltage operation. The first four devices - MCP616, MCP617, MCP618, MCP619 - are unity gain stable and offer rail-to-rail inputs and outputs that allow operation from low supply voltages with large input and output signal swings. These devices meet the need for low offset voltage by combining nonvolatile memory and PNP inputs, resulting in an offset voltage of less than 75 µV (typical). MCP61X devices are available in single, dual, and quad options in PDIP, SOIC and TSSOP packages. MCP618 also features a single amplifier with chip select.
