General Description

The MAX98306 evaluation kit (EV kit) is a fully assembled

and tested PCB that evaluates the MAX98306 stereo 3.2W

Class D amplifier. The EV kit operates from a single 2.6V

to 5.5V DC power supply and is capable of delivering

3.2W into a 4I load. The EV kit accepts a differential

or single-ended audio input and provides differential

outputs for the speaker. The device outputs can be

connected directly to a speaker load for filterless applica-

tions. However, a filter can be added to ease evaluation.

Features

S 2.6V to 5.5V Single-Supply Operation

S Single-Ended or Differential Audio Input

S Five Selectable Gains

S Filterless Operation

S Optional Class D Output Filters for Ease of

Evaluation

S Low-Power Shutdown Mode

S Proven PCB Layout

S Fully Assembled and Tested
