MAX9617–MAX9620 Low-Power, Zero-Drift Operational Amplifiers

The MAX9617–MAX9620 are low-power, zero-drift operational amplifiers designed for portable consumer, medical, and industrial equipment.

The MAX9617–MAX9620 feature rail-to-rail CMOS inputs and outputs and a 1.5MHz GBW, while consuming only 59µA of supply current over time and temperature, and achieving a zero-drift input offset voltage of only 10µV (max). The zero-drift feature of the MAX9617/MAX9618 reduces the large 1/f noise typically seen in CMOS-input op amps, making them ideal for a variety of low-frequency measurement applications.

The MAX9617 and MAX9619 are available in a space-saving 2mm x 2mm, 6-pin SC70 package. The MAX9619 features a power-saving shutdown mode. The MAX9618 is available in a 2mm x 2mm, 8-pin SC70 package. The MAX9620 is available in a 2mm x 2mm, 5-pin SC70 package. All devices are fully specified over the -40°C to +125°C automotive temperature range.
