The MAX9752A evaluation kit (EV kit) is a fully assembled
and tested PC board that evaluates the
MAX9752A as well as the MAX9752B/MAX9752C/MAX9753/MAX9754 ICs. All of these Class D amplifiers
drive stereo bridge-tied-load (BTL) speakers and a
stereo headphone. The ICs' high efficiency make them
well suited for portable audio applications.
The speaker amplifiers operate from a 4.5V to 5.5V DC
power supply, and deliver 2.2W continuous power into a
pair of 4Ω speakers. Three different speaker output configurations
are available for ease of evaluation.
The headphone amplifiers operate from a 3V to 5.5V
DC power supply, and deliver up to 63mW per channel
into a 16Ω stereo headphone. When the switch on the
headphone jack detects the insertion of a headphone,
the MAX9752A automatically enters the headphone
mode from the speaker mode.
The MAX9752A EV kit maximum gain is jumper selectable.
The EV kit features an analog volume control and
an audible alert input for evaluating the MAX9752A/
MAX9752B/MAX9752C. The volume control and audible
alert input can be reconfigured to accept a second audio
source when evaluating the MAX9753, which features a
2:1 multiplexer that allows two audio sources to feed the
EV kit.
