Quick Setup Guide
On opening the TAS5352DDV6EVM package, check to ensure that the following items are included:
• 1 pc. TAS5352DDV6EVM board using one TAS5518PAG and three TAS5352DDV
• 1 pc. TI Input-USB board 2 for interfacing TAS5352DDV6EVM with SPDIF/analog sources and PC for
control
• 1 pc. Signal and Control Interface IDC cable for connection to an I
2
S front-end like the attached TI
Input-USB board 2
• 1 pc. Cable for connecting Input-USB board 2 to a USB port on a PC for TAS5018 control by software
• 1 pc. Power supply cable for a regulated power supply (H-bridge supply)
• 1 pc. AC to DC external 15-V power supply (system supply)
• 4 pc. AC input clips for external 15-V power supply (US, Europe, UK, and Australia)
• 1 pc. PurePath CD-ROM
If any of these items are missing, contact the Texas Instruments Product Information Center nearest you
to inquire about a replacement.
Connect Input-USB board 2 to TAS5352DDV6EVM using the delivered IDC cable.
To power up the EVM, two power supplies are needed. One for system power, logic and gate-drive, and
one for output stage supply. The H-bridge power supply is connected to the EVM using the delivered
white/black power cable. The system power supply is provided in the enclosed external 15-V wall plug
adapter.
Table 2. Recommended Supply Voltages
Description Voltage Limitations Current Requirement Cable
Output stage power supply 0 – 34.5 V 10 A White/Black
CAUTION
Applying voltages above the limitations given in Table 2 may cause permanent
damage to your hardware
Note: The length of power supply cable must be minimized. Increasing length of PSU cable is
equal to increasing the distortion for the amplifier at high output levels and low frequencies.
CAUTION
Both positive and negative speaker outputs are floating and may not be
connected to ground (e.g., through an oscilloscope)
The TAS5518 graphical user interface (GU)I provides easy control of all registers in TAS5518. To install
the GUI, run the setup file from the PurePath CD-ROM.
After installation, turn on the power supplies, and connect the USB cable to the Input-USB board 2.
Start the GUI program from the Windows™ menu. The start-up of the GUI takes a few seconds.
