General Description
Features
The MAX9776 evaluation kit (EV kit) is a fully assembled
and tested printed circuit board (PCB) that evaluates
the MAX9776 ultra-low EMI, 1.5W filterless Class D
audio power amplifier with 80mW DirectDrive™ head-
phone amplifier. The MAX9776 EV kit offers highly pro-
grammable and flexible input and output routing, which
allows many combinations of balanced and single-
ended signals to be connected. The MAX9776 EV kit
also includes Windows® 98SE/2000/XP-compatible
software, which provides a simple graphical user inter-
face (GUI) for exercising the MAX9776’s features.
