MAX97003 Evaluation Kit
Evaluates: MAX97003
General Description
The MAX97003 evaluation kit (EV kit) is a fully assembled
and tested PCB that evaluates the MAX97003 audio
subsystem. The device features a mono Class D speaker
amplifier and a stereo Class H DirectDrive M headphone
amplifier. The EV kit features an on-board microcontroller
for communicating with the I 2 C interface of the device.
Pads are provided for accessing the analog inputs and
amplifier outputs.
The EV kit requires a 2.7V to 5.5V power supply. The
on-board LDO generates an additional 1.8V supply from
the USB 5V supply. The EV kit delivers 1W into an 8 I
speaker, and 32mW/channel into a 32 I headphone.
Windows XP M -, Windows Vista M -, and Windows M 7-compat-
ible EV kit software is provided to facilitate configuration.
The EV kit software controls the on-board microcontroller
over USB, which generates I 2 C commands.
