MAX9830A Evaluation Kit
General Description
Features
S Industry-Leading Quiescent Current
1.6mA (V = 5V), 1.2mA (V = 3.6V)
The MAX9830A evaluation kit (EV kit) is a fully assembled
and tested circuit board that uses the MAX9830A filter-
less Class D amplifier to drive a mono bridge-tied-load
(BTL) speaker in portable audio applications. Designed
to operate from a 2.6V to 5.5V DC power supply, the EV
kit is capable of delivering 2W into a 4I load. The EV
kit accepts differential or single-ended input signals.
The MAX9830A EV kit also evaluates the MAX9830B–
MAX9830E.
