System/Evaluation Kit
General Description
Features
The MAX9760 evaluation system (EV system) consists
of a MAX9760 evaluation kit (EV kit) and a companion
Maxim System Management Bus (SMBus™) interface
board. The MAX9760 EV kit is also capable of evaluat-
ing the MAX9761/MAX9762/MAX9763.
ꢀ 4.5V to 5.5V Single-Supply Operation
ꢀ 3W Stereo Bridge-Tied-Load (BTL) Amplifier
ꢀ 100dB Power-Supply Rejection Ratio
ꢀ SMBus/I2C-Compatible 2-Wire Serial Interface
ꢀ 2:1 Stereo Input MUX
The MAX9760 EV kit is a fully assembled and tested
surface-mount circuit board that evaluates the
MAX9760 3W stereo audio power amplifier plus head-
phone driver. The EV kit is designed to be driven by
any stereo audio source such as a CD player. The EV
kit includes RCA jacks on the inputs, a 3.5mm head-
phone jack, and terminal blocks on the outputs to facili-
tate easy connections to the circuit board. The EV kit
includes Windows®98/2000/XP-compatible software,
which provides a user interface for exercising the
MAX9760’s features.
ꢀ Selectable Bass-Boost Circuitry
ꢀ No Detectable Clicks or Pops
ꢀ Easy-to-Use, Menu-Driven Software
ꢀ Assembled and Tested
ꢀ Software-Controlled Mute, Shutdown, Input
Selection, and Gain
The Maxim SMBus interface board (MAXSMBUS) allows
an IBM-compatible PC to use its parallel port to emulate
an SMBus/I2C™ 2-wire interface. Windows 98/2000/XP-
compatible software provides a user-friendly interface to
exercise the MAX9760 features. The program is menu
driven and offers a graphical user interface (GUI) with
control buttons and a status display.
ꢀ Automatic Headphone-Sensing Circuitry
ꢀ Includes Windows 98/2000/XP-Compatible
Software and Demo PC Board
ꢀ Evaluates the MAX9760–MAX9763
The MAX9760EVSYS includes both the EV kit and the
MAXSMBUS interface board. Order the MAX9760EVKIT
if you already have an SMBus interface. The MAX9761
EV kit functions as a stand-alone unit, the MAXSMBUS
interface is not required.

Note: To evaluate the MAX9762, or MAX9763, request a
MAX9762ETI or MAX9763ETI free sample with the
MAX9760EVKIT. To evaluate the MAX9761, order the
MAX9761EVKIT. The MAX9760 EV kit software is provided with
the MAX9760EVKIT; however, the MAXSMBUS board is
required to interface the EV kit to the computer when using the
included software.
