Product Details

The MAX9742 evaluation kit (EV kit) is a fully assembled and tested PCB that configures the MAX9742 Class D amplifier to drive 2 x 20W into a pair of 8Ω speakers for audio applications. The EV kit operates from a 20V to 40VDC power supply. The EV kit is configured for a +26dB gain. The MAX9742 EV kit accepts single-ended or differential input signals, and provides a pair of single-ended outputs.

The MAX9742 EV kit provides a shutdown input pad to control the shutdown mode of the MAX9742. The shutdown mode reduces power consumption and extends battery life. The EV kit also provides a mute input pad to control the mute mode of the MAX9742. The EV kit includes convenient audio input and output connectors, and the required output filters to ease evaluation.
