MAX98400BEVKIT+(U2): 12Wx2 @ 8Ω, 8~28Vin, Filtered

Summary

The MAX98400B evaluation kit (EV kit) configures the
MAX98400B Class D amplifier to drive 2x12W into a pair
of 8I speakers in stereo mode for audio applications.
The EV kit operates from an 8V to 28V DC power supply.
The EV kit has a programmable gain and the jumper settings
default to a +20.1dB gain. The EV kit accepts a pair
of single-ended or differential input signals and provides
two sets of differential outputs for speakers.

The EV kit has two independent amplifier circuits, demonstrating
direct speaker driving (for low component
count) and filtered output driving (for ease of evaluation).
The EV kit comes with two MAX98400BETG+ devices
installed.

The EV kit provides an option to control the limiter,
thermal foldback, input configuration, gain, and shutdown
mode of the device. The EV kit includes convenient
audio input and output connectors.
