MAX97001 Evaluation Kit

Evaluates: MAX97001

General Description

The MAX97001 evaluation kit (EV kit) is a fully assembled

and tested PCB that evaluates the MAX97001 mono

Class D audio power amplifier and stereo Class H

DirectDrive

headphone amplifier communicating over

a 2-wire I

C interface. The EV kit features an on-board

microcontroller for communicating with the I

C interface

of the MAX97001. PCB pads are provided for accessing

the analog inputs and amplifier outputs.

The MAX97001 EV kit requires a 2.7V to 5.5V supply for

PVDD and a 1.8V supply for VDD.

Windows

2000-, Windows XP

-, and Windows Vista

compatible software is provided to facilitate configura-

tion. The software controls an on-board microcontroller

over USB, which generates I

C commands.

A New Hardware Found window pops up when installing the USB driver for the first time. If a window is not seen that is similar to the one described above after 30s, remove the USB cable from the board and reconnect it. Administrator privileges are required to install the USB device driver on Windows.

Graphical User Interface (GUI) The MAX97001 EV kit software GUI (Figures 1 and 2) provides a convenient way to test the features of the MAX97001. Figure 1 displays the MAX97001 EV kit software’s Main Control tab sheet, while Figure 2 displays the Registers tab sheet. Actions on the two tabs generate I2C commands to update the MAX97001 internal memory registers.

Evaluates: MAX97001 MAX97001 Evaluation Kit Software Startup Upon starting the program, the MAX97001 EV kit software automatically searches for the USB interface circuit and then for the MAX97001 device address. The MAX97001 EV kit enters the normal operating mode when the USB connection is detected and has found the device address. If the USB connection is not detected, the software prompts the user to retry or enter the demo mode.
