On opening the TAS5132DDV6EVM package, ensure that the following items are included:
•
1 pc. TAS5132DDV6EVM board using one TAS5086DBT and two TAS5132DDV.
•
1 pc. TI Input-USB board for interfacing TAS5132DDV6EVM with SPDIF/analog sources and PC for
control.
•
1 pc. Signal interface IDC cable for connection to an I
2
S front-end like the attached TI Input-USB
board.
•
1 pc. Control interface IDC cable for connection to an I
2
C front-end like the attached TI Input-USB
board.
•
1 pc Cable for connecting Input-USB board to a USB port on a PC for TAS5086 control by software.
•
1 pc. Power supply cable for two regulated power supplies (H-bridge and system supply).
•
1 pc. PurePath CD-ROM
If any of these items is missing, contact the Texas Instruments Product Information Center nearest you to
inquire about a replacement.
Connect Input-USB board to TAS5132DDV6EVM using the two delivered IDC cables.
To power up the EVM, two power supplies are needed. One for system power, logic, and gate-drive, and
one for output stage supply. Power supplies are connected to the EVM using delivered power cable
red/black, white/black.
A single 15-V to 18-V power supply can be used if the user connects black/black to GND and red/white to
15/18 V.

CAUTION
Applying voltages above the limitations given in
can 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)
