General Description
The MAX98365 evaluation system (EV system) is a
fully assembled and tested system that evaluates the
MAX98365A/B/C/D mono Class-D audio amplifier. The
EV system consists of the MAX98365 Development
Board (DEV board), Maxim’s 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. MAX98365A and
MAX98365C support the standard I
2
S interface, and
MAX98365B and MAX98365D support standard left-jus-
tified mode. All MAX98365 variants support an 8-channel
TDM digital audio interface.
The AUDINT3 board provides a USB-to-PCM interface
in addition to a 1.8V VDD supply needed to evaluate the
DEV board. The MAX98365 DEV board requires one
additional supply input, 3V to 14V (PVDD) when evaluat-
ing using the AUDINT3 board.

board and the AUDINT3 board.
