The MAX98500 evaluation kit (EV kit) is a fully assembled
and tested circuit board that uses the MAX98500 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 delivers 2.2W into an 8I load. The EV kit accepts
differential or single-ended input signals, features three
selectable gain settings (6dB, 15.5dB, and 20dB), and
provides separate speaker and boost shutdown inputs.
