Product Details

The MAX9617–MAX9620 are low-power, zero-drift operational amplifiers available in space-saving SC70 packages. They are designed for use in portable consumer, medical, and industrial applications.

The MAX9617–MAX9620 feature rail-to-rail CMOS inputs and outputs, a 1.5MHz GBW at just 59µA supply current and 10µV (max) zero-drift input offset voltage over time and temperature. The zero-drift feature reduces the high 1/f noise typically found in CMOS input operational amplifiers, making it useful for a wide 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 specified over the -40°C to +125°C automotive operating temperature range.
