Product Details
The MAX98388/MAX98389 evaluation system (EV system) is a fully assembled and tested system that evaluates the MAX98388 or MAX98389 Class-D audio amplifier. The EV system consists of either the MAX98388 or MAX98389 development board (DEV board), Analog Devices 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. Both devices support standard I2S, left-justified, and TDM digital audio interfaces.
The AUDINT3 board provides a USB-to-PCM interface in addition to a 1.8V VDD supply needed to evaluate the DEV board. The DEV board requires one additional supply input, 2.3V to 10V (PVDD) when evaluating using the AUDINT3 board. Figure 1 details the DEV boards.
