Product Details

The MAX98366 evaluation system (EV system) is a fully assembled and tested system that evaluates the MAX98366A/B/C/D mono Class-D audio amplifier with ultrasound support. The EV system consists of a MAX98366 Development Board (DEV board), an Audio Interface Board III (AUDINT3), and a USB cable.

It is recommended that the DEV board be evaluated with the AUDINT3 board, as an EV system. MAX98366A and MAX98366C support the standard I2S interface, and MAX98366B and MAX98366D support standard left-justified mode. All MAX98366 variants support an 8-channel TDM digital audio interface.

The AUDINT3 board provides a USB-to-PCM interface and a 1.8V VDD supply needed to evaluate the DEV board. The MAX98366 DEV board requires one additional supply input, 3V to 15V (PVDD) when evaluating using the AUDINT3 board. Figure 1 details the DEV board and the AUDINT3 board.
