The MAX9714 evaluation kit (EV kit) is a fully assembled
and tested circuit board that contains the MAX9714 fil-
terless class D amplifier. The EV kit is capable of deliv-
ering 6W into an 8Ω load and is designed to operate
from a 10V to 25V DC power supply. The MAX9714 EV
kit accepts differential or single-ended input signals
and provides an option to select between different
switching frequencies.
The MAX9714 EV kit can also evaluate the MAX9704
15W, filterless, class D amplifier.
19-3227; Rev 1; 4/05
