Product Details

The MAX44248 evaluation kit (EV kit) provides a proven design to evaluate the MAX44248 low-power, dual op amps in an 8-pin µMAX® package. The EV kit circuit is preconfigured as noninverting amplifiers, but can be adapted to other topologies by changing a few components. The component pads use a 0805 package, making them easy to solder and replace. The EV kit comes with a MAX44248AUA+ installed.
