MAX9791A Evaluation Kit

Evluates:MX791A

General Description

Features

♦ No DC-Blocking Output Capacitors Required at

The MAX9791A evaluation kit (EV kit) demonstrates the

MAX9791A IC, which combines a stereo Class D power

amplifier, a DirectDrive^®stereo headphone amplifier,

and a 120mA, 4.75V low-dropout regulator (LDO) for

notebook, tablet PC, and portable media player appli-

cations. Maxim’s DirectDrive technology eliminates the

need for bulky DC-blocking capacitors at the output of

the headphone amplifier.

Headphone Output

♦ Speaker and Headphone Operation

Speaker: 2W Stereo Output

Headphone: 180mW DirectDrive Stereo Output

♦ Wake-on-Beep Function

♦ 120mA, 4.75V LDO

♦ Lead-Free and RoHS Compliant

♦ Fully Assembled and Tested

The EV kit is configured for a 12dB speaker amplifier

gain and a 0dB headphone amplifier gain. It is designed

to operate from a 4.5V to 5.5V speaker supply and an

optional separate 2.7V to 5.5V headphone supply. The

EV kit is capable of delivering up to 2W into a pair of 4Ω

speakers and 180mW into a 32Ω headphone load.
