Description

The MAX9708 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that configures the MAX9708 Class D amplifier to drive 2 x 21W into a pair of 8 speakers in stereo mode, or 1 x 42W into a single 4 speaker in mono mode for audio applications. The EV kit’s speaker outputs can be filterless to minimize the circuit area or can be filtered to ease evaluation. The EV kit operates from a 10VDC to 18VDC power supply. The MAX9708 EV kit accepts single-ended or differential input signals, and provides fully differential outputs. The EV kit provides an option to select between +22dB, +25dB, +29.5dB, or +36dB gains. The MAX9708 EV kit offers an option to select between fixed-frequency modulation (FFM) mode or spread-spectrum modulation (SSM) mode. The MAX9708 EV kit provides a thermal flag that can be programmed for eight different thermal thresholds. The MAX9708 EV kit can be synchronized with an external clock, and the EV kit provides a synchronous output that allows units to be cascaded and frequency locked in a multiamplifier system.
