Product Details

The MAX9945 evaluation kit (EV kit) provides a proven design to evaluate the MAX9945 low-noise, MOS-input, low-power op amp in an 8-pin µMAX® package. Various test points are provided for easy evaluation. The EV kit circuit is preconfigured as a transimpedance amplifier (TIA), but can easily be adapted to act as a noninverting, inverting, or differential amplifier by changing a few components. MOS-input bias currents, low input-voltage noise, and rail-to-rail output stage make this device ideal for photodiode transimpedance amplifiers, piezo buffers, and audio line out applications. The components have pads that accommodate 0805 packages, making them easy to solder and replace. The MAX9945 EV kit PCB comes with a MAX9945AUA+ installed. Note that the MAX9945 is also available in a 3mm x 3mm TDFN package.
