The MAX9715 evaluation kit (EV kit) is a fully assembled
and tested PC board that uses the MAX9715 filterless
Class D amplifier to drive a pair of stereo bridge-tied-
load (BTL) speakers in portable audio applications.
Designed to operate from a 5V DC power supply, the EV
kit is capable of delivering 2.3W per channel at 1%
THD+N into a pair of 4Ω speaker loads. Three different
output configurations are available for ease of evaluation.
The MAX9715 EV kit accepts single-ended input sig-
nals, and provides fully differential outputs. The EV kit
also provides an option to select between 9dB or
10.5dB gains.
