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 8 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.
