Product Details

The MAX97000 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX97000 mono Class D audio power amplifier and stereo Class H DirectDrive® headphone amplifier communicating over a 2-wire I²C interface. The EV kit features an on-board microcontroller for communicating with the I²C interface of the MAX97000. Pads are provided for accessing the analog inputs and amplifier outputs.

The MAX97000 EV kit requires a 2.7V to 5.5V power supply. The on-chip LDO generates an internal 1.8V supply from the 2.7V to 5.5V supply.

Windows® 2000-, Windows XP®-, and Windows Vista®-compatible software is provided to facilitate configuration. The software controls an on-board microcontroller over USB, which generates I²C commands.
