Product Details

The MAX9741 evaluation kit (EV kit) is a fully assembled and tested circuit board that configures the MAX9741 Class D amplifier to drive 12W into a pair of 8Ω speakers in stereo for audio applications. The EV kit's speaker outputs can be filterless to minimize circuit area, can be filtered to ease evaluation.

The MAX9741 EV kit operates from a 10V to 25V DC power supply. The EV kit accepts differential or single-ended input signals, and provides fully differential outputs. The EV kit provides an option to select between +13dB, +16dB, +19.1dB, or +29.6dB gains. The MAX9741 EV kit offers an option to select between fixed-frequency modulation (FFM) mode or spread-spectrum modulation (SSM) mode.
