The from Products is an evaluation kit EV kit for the MAX98400B. This EV kit configures the MAX98400B class D amplifier to drive 2x12W into a pair of 8ohm speakers in stereo mode for audio applications. It has a programmable gain and the jumper settings default to a +20.1dB gain. The kit accepts a pair of single ended or differential input signals and provides two sets of differential outputs for speakers. It 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+ 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. It is typically used in LCD monitors, LCD/PDP televisions, MP3 docking stations and notebook PCs.
