The MAX9768 evaluation kit (EV kit) is a fully assembled
and tested printed-circuit board (PCB) that demon-
strates the capabilities of the MAX9768 mono 10W
Class D speaker amplifier with volume control. The
MAX9768 EV kit also includes Windows
compatible software that provides a simple graphical user
interface (GUI) for exercising the features of the MAX9768.
The MAX9768 evaluation system (EV system) consists of the
MAX9768 EV kit and a companion CMAXQUSB serial-
interface board. The CMAXQUSB interface board allows
a PC to control an I
the MAX9768 EV system (MAX9768EVCMAXQU+) for a
complete PC-based evaluation of the MAX9768. Order
the MAX9768 EV kit (MAX9768EVKIT+) if you already
have a MAX9768-compatible serial interface.
