MAX98425AEVSYS#

MAX98425AEVSYS# is a MAX98425A evaluation system (without voltage feedback and current monitoring). This evaluation system (EV system) is a fully assembled and tested system that evaluates theMAX98425A stereo Class-D audio amplifier. The EV system consists of the MAX98425A 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. MAX98425A supports the standard I2S interface, left justified, and Time-division multiplexing (TDM) digital audio interfaces. The AUDINT3 board provides a USB-to-PCM interface in addition to 1.8V AVDD and DVDD supplies needed to evaluate the DEV board. Note that if AUDINT3 is not used, AVDD and DVDD can be supplied externally or by an on-board LDO with a few 0Ω resistor changes. The MAX98425A DEV board requires two additional supply inputs, 2.4V to 5.5V (VBAT) and 3V to 22V (PVDD).
