The MAX9700B evaluation kit (EV kit) is a fully assembled
and tested circuit board that uses the MAX9700B filter-
less 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 1.2W into an 8Ω load.
The EV kit accepts differential or single-ended input
signals. The EV kit provides an option to select between
different switching frequency modes of operation. The
MAX9700B EV kit also evaluates the MAX9700A/
MAX9700C/MAX9700D and the MAX9712.
