Ultra-Low Power, Zero-Drift Precision Op Amps in SC70 Packages
Maxim Confidential 
MyMaxim SubscriptionsProduct Details
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.

Amplifier Offset and Gain Error in a Signal Chain Description
The MAX9617 evaluation kit (EV kit) provides a proven design to evaluate the MAX9617 low-power, zero-drift operational amplifier (op amp) in a 6-pin SC70 package. The EV kit circuit is preconfigured as a noninverting amplifier, but can easily be adapted to other topologies by changing a few components. Low power, zero drift, input offset voltage, and rail-to-rail input/output stages make this device ideal for a variety of low-frequency measurement applications. The component pads accommodate 0805 packages, making them easy to solder and replace. The MAX9617 EV kit comes with a MAX9617AXT+ installed.
