2.6V to 5.5V, 2A DC supply
4I speaker
Mono audio signal source
Verify that shunts are installed as follows:
Connect the power-supply positive and negative
outputs to the PVDD and PGND PCB pads on the
EV kit, respectively.
Verify that the audio source output is disabled.
Connect the mono audio source between the
INPUT+ and INPUT- pads on the EV kit.
Connect the speaker across the OUT+ and OUT-
test points.
Set the power-supply output to 5V.
Enable the power-supply output.
Enable the audio source.
Verify that the speaker is playing the audio source
signal.

The MAX98300 EV kit features the MAX98300 filterless
Class D amplifier IC, which is designed to drive a mono
speaker in portable audio applications. The EV kit comes
with a MAX98300 IC in an 8-pin TDFN package. The EV
kit operates from a DC power supply that provides 2.6V
to 5.5V and 2A of current. The EV kit accepts a differen-
tial or single-ended audio input. The audio input source
is amplified to drive 2.6W into a 4I speaker.
Jumper JU1 enables or disables the speaker amplifier.
Jumper JU2 configures the EV kit inputs for single-ended
or differential operation. The amplifier overall gain can
be set between 0dB and +12dB using jumper JU3. The
EV kit provides a set of differential outputs. The device
outputs (OUT+, OUT-) can be connected directly to a
speaker load without any filtering and up to 60cm of
cable. However, filter components can be added to ease
evaluation. See the Output Filtering Options section for
additional information.
Jumper JU1 enables or disables the audio speaker
amplifier. See Table 1 for jumper JU1 configuration.
