For Use With
MAX98502
The MAX98502 evaluation kit (EV kit) is a fully assembled
and tested circuit board that uses the MAX98502 boost-
ed Class D amplifier to drive a mono bridge-tied-load
(BTL) speaker in portable audio applications. Designed
to operate from a 2.5V to 5.5V DC power supply, the EV
kit is capable of delivering 2.2W into an 8I load or 4W
into a 4I load. The EV kit accepts differential or single-
ended input signals, features selectable gain, and sepa-
rate speaker and boost shutdown inputs.
