MAX97200A Evaluation Kit

Evaluates: MAX97200A/MAX97200B

General Description

The MAX97200A evaluation kit (EV kit) is a fully

assembled and tested circuit board that evaluates the

MAX97200A. The MAX97200A is a 20mW Class G head-

phone amplifier that employs Maxim’s second-generation

DirectDrive

technology.

The MAX97200A EV kit provides 3dB gain, is powered

from a 1.8V single power supply, and includes a shut-

down input. The MAX97200A EV kit also evaluates the

MAX97200B. Request a free MAX97200B IC sample

from the factory when ordering the MAX97200B EV kit.

Procedure

The MAX97200A EV kit is fully assembled and test-

ed. Follow the steps below to verify board operation.

Caution: Do not turn on the power supply until all

connections are completed.

1) Verify that shunts are installed as follows:

JU1: Installed (device enabled)

2) Set the power-supply output to 1.8V.

3) Disable the power-supply output.

4) Connect the power-supply ground to the GND pad

and the power-supply positive output to the VIN pad

on the EV kit.

5) Connect the headphones to the stereo headphone

jack (J1) provided on the EV kit.

6) Verify that the audio source output is disabled.

7) Connect the left channel of the stereo audio source

to INL.

8) Connect the right channel of the stereo audio

source to INR.

9) Connect the ground of the stereo audio source to

GND.

10) Enable the stereo audio source.

11) Enable the power-supply output.

12) Verify that the headphones are playing the audio

source signal.
