Low-power op amps

Microchip has announced the MCP6V01/2/3 (MCP6V0X) auto-zero operational amplifiers.

The low-power units feature a self-correcting architecture that enables ultra-high precision, with an input offset voltage of 2 µV maximum.

They also feature high common-mode rejection, rail-to-rail input/output and low quiescent current, making them suitable for portable, battery-powered instrumentation devices, such as those used in the industrial and medical markets.

With their low operating voltage range of 1.8 to 5.5 and low typical quiescent current of 300 µA, the op amps can run from two 1.5 V cells with full battery use.

The devices feature a self-correcting architecture that results in fewer errors, especially at higher gains. Additionally, their rail-to-rail input/output structure enables greater dynamic range. The combined result of these features is better system performance at all operating voltages.
