Unpacking the EVM

On opening the TAS5342DDV6EVM package, ensure that the following items are included:
• 1 pc. TAS5342DDV6EVM board using one TAS5508BPAG and three TAS5342DDV.
• 1 pc. TI Input USB Board 2 for interfacing TAS5342DDV6EVM with S/PDIF/analog sources and PC for
control.
• 1 pc. Signal and Control Interface IDC cable for connection to a TI Input USB Board 2.
• 1 pc. Cable for connecting Input-USB board to a USB port on a PC for TAS5508B control by software.
• 1 pc. Power supply cable for a regulated power supply (H-bridge supply).
If any of the items are missing, contact the Texas Instruments Product Information Center nearest you to
inquire about a replacement.
Connect Input-USB board to TAS5342DDV6EVM using the delivered IDC cable.
2.3 Power Supply Setup
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
power cable White/Black, White/Black. The system, logic and gate drive power supply must be supplied
from an external 15-V, 1-A adapter. The characteristics of this adapter can be found in

damage to your hardware.
NOTE: The length of the power supply cable must be minimized. Increasing the length of the PSU
cable is equal to increasing the distortion for the amplifier at high output levels and low
frequencies.
2.4 Speaker Connection
Both positive and negative speaker outputs are floating and may not be
connected to ground (e.g., through an oscilloscope).
