The MAX9765 evaluation system (EV system) consists of
a MAX9765 evaluation kit (EV kit) and a companion
Maxim CMAXQUSB board.
The MAX9765 EV kit is a fully assembled and tested surface-mount printed circuit board (PCB) that evaluates the
MAX9765 750mW stereo audio power amplifier plus
headphone driver and microphone amplifier. The EV kit is
designed to be driven by any stereo audio source such
as a CD player. The MAX9765 EV kit includes RCA jacks
and a 3.5mm microphone jack on the inputs as well as a
3.5mm headphone jack and terminal blocks on the output
to facilitate easy connections to the PCB. The MAX9765
EV kit includes Windows® 98SE/2000/XP-compatible software,
which provides a user interface for exercising the
MAX9765 features.
The CMAXQUSB interface board allows a PC to use its
USB port to emulate an SMBus™/I²C-compatible
2-wire interface. Windows 98SE/2000/XP-compatible
software provides a user-friendly interface to exercise
the MAX9765 features. The program is menu driven
and offers a graphic interface with control buttons and
status display.
The MAX9765 EV system (MAX9765EVCMAXQU)
includes both the MAX9765 EV kit and the CMAXQUSB
interface board. Order only the MAX9765 EV kit if you
already have an SMBus interface board.
