2.3 Power Supply Setup
2.4 Speaker Connection
2.5 GUI Software Installation
Quick Setup Guide
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 power supplies are connected to the EVM using the delivered power
cable Red/Black, White/Black.
Table 2. Recommended Supply Voltage
Description Voltage Limitations Current Requirement Cable
System power supply 15 V to 28 V 0.3 A Red/Black
Output stage power supply 0 V to 28 V 2.0 A White/Black
CAUTION
Applying voltages above the limitations listed in the table above may cause
permanent 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.
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 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.
Start the GUI program from the windows menu. Start-up of the GUI will take a few seconds.
