1.1 Additional Documentation
• Personal Computer (PC) Configuration Tool for TAS5086 (TAS5086 GUI version 4.0 or later). This
software comes on the compact disk in the EVM package.
2 Overview
The TAS5102EVM and TAS5103EVM packages are composed of two separate modules, the HPL-MC012
Modulator/Controller Module and the TAS5102EVM or TAS5103EVM Amplifier Module. They are
designed so that the user can separate the two modules and connect the TAS5102EVM or TAS5103EVM
Amplifier Module into a target system via a ribbon cable. Keep this ribbon cable as short as possible to
avoid degradation in the PWM signals.
The TAS5102 and TAS5103 customer evaluation amplifier modules each demonstrate two audio
integrated circuits — the TAS5086 and the TAS5102 or TAS5103 from Texas Instruments (TI).
The TAS5086DBT is a high-performance, 32-bit (24-bit input), multichannel PurePath Digital™ pulse width
modulator (PWM) based on Equibit™ technology with fully symmetrical AD modulation scheme. It accepts
an input sample rate from 32 kHz to 192 kHz. The device also has digital audio processing (DAP) that
provides bass management, advanced performance, and a high level of system integration.
The TAS5102 is a compact, high-power, digital amplifier power stage designed to drive an 8- Ω
loudspeaker up to 20 W/channel at 10% THD+N. It contains integrated gate-drive, four matched and
electrically isolated enhancement-mode N-channel power DMOS transistors, and protection/fault-reporting
circuitry. The DAD package has a PowerPAD™ package on the top side for heat transfer through a heat
sink. The heat sink in this design is for evaluation purposes only.

Overview
The TAS5103 is a compact, high-power, digital amplifier power stage designed to drive an 8- Ω
loudspeaker up to 15 W/channel at 10% THD+N. It contains integrated gate-drive, four matched and
electrically isolated enhancement-mode N-channel power DMOS transistors, and protection/fault-reporting
circuitry. The DAP package has a PowerPAD™ package on the bottom side for heat transfer through the
printed-circuit board.
Either of these EVMs plus the HPLMC-012 form a complete two-channel, digital audio amplifier system
which includes digital input (S/PDIF), control interface (via USB) to PC and DAP (digital audio processor)
features like digital volume control, bass management, and input and output multiplexers.
This EVM is designed to illustrate a low-cost approach to an amplifier design using this device. Improved
performance, at increased cost, can be achieved with a high-performance configuration.
2.1 TAS5102EVM and TAS5103EVM Features
• Modular approach comprised of TAS5102EVM or TAS5103EVM amplifier modules and HPL-MC012
modulator/controller module
• Two-channel evaluation module.
• Self-contained protection system (short-circuit and thermal).
• Standard I2S and I2C control via SPDIF and USB
• Double-sided, plated-through printed-circuit board (PCB) layout
• Single power supply operation

3 Quick-Setup Guide
This section describes the TAS5102/3EVM board in regards to power supplies and system interfaces. It
provides information regarding handling and unpacking, absolute operating conditions, and a description
of the factory default switch and jumper configuration.
The section also provides a step-by-step guide to configuring the TAS5102/3EVM for device evaluation.
3.1 Electrostatic Discharge Warning
Many components on the TAS5102/3EVM are susceptible to damage by electrostatic discharge (ESD).
Customers are advised to observe proper ESD handling precautions when unpacking and handling the
EVM, including the use of a grounded wrist strap at an approved ESD workstation.
Failure to observe ESD handling procedures can result in damage to EVM
components.
3.2 Unpacking the EVM
On opening the TAS5086-TAS5102EVM or TAS51033EVM package, ensure that the following items are
included:
• 1 pc. TAS5102/3 EVM Power Stage Board
• 1 pc. HPL-MC012 Modulator/Input Board
• Because this system has standard connectors, no cables are supplied
• 1 pc. TAS5102/3EVM CD-ROM.
If any of these items are missing, contact the Texas Instruments Product Information Center nearest you
to inquire about a replacement.
Connect the Modulator/Input board to the Power Stage board with the docking connectors on each board.
Use care because this connector is not keyed.

3.3 Power Supply Setup
To power up the EVM, one power supply is needed for system power, logic and gate-drive, and for output
stage supply. The power supply is connected to the EVM with banana cables or stripped insulated wire.

damage to your hardware.
Figure 3. TAS5086 GUI Window
From the files menu, load the configuration file:
TAS5102 EVM Configuration.cfg
The file is located on the TAS5102/3EVM CD-ROM. This file contains all settings for a default setup of the
EVM.
For easy access of the file, it is recommended to copy the files into directory where the GUI is installed.
Default is C:\Program Files\Texas Instruments Inc\TAS5086\.
For more advanced use of the GUI and the features of the TAS5086 modulator, see the GUI User’s Guide
and the TAS5086 data sheet (SLES131 ). The GUI User's Guide can be accessed by clicking on Help in
the toolbar and then selecting User's Guide in the drop-down menu.
