The MAX9850 evaluation system (EV system) consists
of a MAX9850 evaluation kit (EV kit), a companion
Maxim command module (CMOD232) interface board,
and software.
The MAX9850 EV kit is a fully assembled and tested
surface-mount printed circuit board (PCB) that evalu-
ates the MAX9850 headphone stereo DAC with inte-
grated headphone driver. The EV kit is designed to be
driven by any digital audio Sony/Philips Digital Interface
(S/PDIF) audio source and can be optionally configured
to accept generic digital audio or I
nals. The EV kit provides RCA jacks for connecting ana-
log input signals. A 3.5mm headphone jack allows for
easy connection of headphones to the PCB.
The Maxim command module interface board
(CMOD232) allows a PC to use its serial port to emulate
an I
ble software, which can be downloaded from the
Maxim website, provides a user-friendly interface to
exercise the features of the MAX9850. The program is
menu driven and offers a graphical user interface (GUI)
with control buttons and a status display.
The MAX9850 EV system (MAX9850EVCMOD2#)
includes both the EV kit and the CMOD232 interface
board. Order the MAX9850 EV kit (MAX9850EVKIT#) if
you already have a command module interface.
