MAX98050 Evaluation System
General Description
The MAX98050 evaluation system (MAX98050EVSYS#)
evaluates the MAX98050, a low-power, high-performance
audio CODEC with integrated low-latency digital filters
for wireless hearables, headsets, and headphones. The
EV system is comprised of two MAX98050 Development
Boards (DEV boards), Maxim's Audio Interface Board III
(AUDINT3), Maxim's Dual EVKit Adapter board, and a
USB cable. In addition to the hardware, the MAX98050
Evaluation Software and Hearable Sound Studio Basic
software are available for download.
It is recommended that the DEV boards be evaluated with
the AUDINT3 board as an EV system. The EV system can
be configured as Mono Hardware Setup (1 DEV board)
or Stereo Hardware Setup (2 DEV boards). MAX98050
2
supports standard I S, left-justified, and TDM digital audio
2
interfaces, as well as I C for control.
The AUDINT3 board provides all of the necessary supply
voltages for proper operation of MAX98050. In addition,
the AUDINT3 provides the USB-to-PCM and USB-to-I
interfaces that are needed to evaluate the system. The
Simplified EV System Block Diagrams show details of the
DEV boards, Dual EVKit Adapter board and connection
with the AUDINT3 board.
