MAX98400AEVKIT+

The MAX98400AEVKIT+ is an evaluation kit for MAX98400A. The EV kit configures the MAX98400A Class D amplifier to drive 2x20W into a pair of 8ohm speakers in stereo mode or 1x40W into a 4ohm speaker in mono mode for audio applications. The EV kit operates from an 8V to 28V DC power supply. The EV kit is configured for +20.1dB gain. It accepts a pair of single ended or differential input signals and provides two sets of differential outputs for speakers. It has two independent MAX98400A circuits, demonstrating direct speaker driving (for low component count) and filtered output driving (for ease of evaluation). The EV kit comes with two MAX98400AETX+ devices installed. The EV kit includes convenient audio input and output connectors. It is used in LCD monitors, LCD/PDP televisions, MP3 docking stations and notebook PCs.
