Quick-Setup Guide
On opening the TAS5162DDV6EVM package, check to ensure that the following items are included:
• 1 pc. TAS5162DDV6EVM board using one TAS5086DBT and two TAS5162DDV.
• 1 pc. TI Input-USB board for interfacing TAS5162DDV6EVM 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 Digital™ 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 Input-USB board to TAS5162DDV6EVM using the two delivered IDC cables.
Two power supplies are required to power up the EVM: one for system power, logic, and gate-drive, and
one for output stage supply. Power supplies are connected to the EVM using the delivered power cable
Red/Black, White/Black.
Table 2. Recommended Supply Voltages
Description Voltage Limitations Current Requirement Cable
System power supply 15–20 V 0.3 A Red/Black
Output stage power supply 0–50 V 10 A White/Black
CAUTION
Applying voltages above the limitations given in Table 2 may cause
permanent damage to the hardware.
Note: The length of power supply cable must be minimized. Increasing the length of the
PSU cable is equivalent 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 TAS5086 GUI provides easy control of all registers in the TAS5086. To install the GUI, run setup file
from the PurePath™ CD-ROM.
After installation, turn on the power supplies and connect the USB cable to the Input-USB board.
