MAX9723D Evaluation Kit/Evaluation System
General Description
The MAX9723D evaluation kit (EV kit) is a fully assem-
bled and tested PCB that evaluates the MAX9723
stereo DirectDrive^TM headphone amplifier with
BassMax, volume control, and I²C. The MAX9723D EV
kit operates from a single 1.8V to 3.6V power supply,
and is capable of delivering 60mW into a 16Ω load.
The MAX9723D evaluation system (EV system) includes
a MAX9723D EV kit, Windows 98SE/2000/XP-compati-
ble software, and a Maxim system command module.
The software’s graphical user interface (GUI) allows
easy control of the MAX9723D’s I²C interface, adjusting
settings such as BassMax and volume.
Order the complete EV system (MAX9723DEVC-
MODU+ or MAX9723DEVCMOD2+) for a comprehen-
sive evaluation of the MAX9723A/MAX9723B/
MAX9723C/MAX9723D using a PC. Order the EV kit
(MAX9723DEVKIT+) if the CMODUSB+ or CMOD232+
system command module has already been purchased
with a previous Maxim EV system, or for custom use in
other microcontroller-based (µC) systems.
The EV kit comes with the MAX9723DETE+ installed.
Contact the factory for free samples of the pin-compati-
ble MAX9723A/MAX9723B/MAX9723C to evaluate
these parts.

Note: The MAX9723D EV kit software is included with the
MAX9723D EV kit, but is designed for use with the complete EV
system. The EV system includes a Maxim system command
module (CMODUSB+ or CMOD232+) and the EV kit. If the
Windows software will not be used, the EV kit board can be pur-
chased without the Maxim system command module.
