Quick Setup Guide

CAUTION

Failure to observe ESD handling procedures can result in damage to EVM

components.

2.2 Unpacking the EVM

Upon opening the TAS5612L-TAS5614LDDVEVM package, check to make sure that the following items

are included:

•

1 pc. TAS5612L-TAS5614LDDVEVM using 1 TAS5538DGG and 1 TAS5612LDDV or TAS5614LDDV.

1 pc. TI Input-USB Board 3 for interfacing TAS5612L-TAS5614LDDVEVM to SPDIF/analog sources

and PC for control.

•

1 pc. Signal and Control Interface IDC cable for connection to an I²S front-end like the Input-USB

Board 3.

•

1 pc. Cable for connecting Input-USB Board 3 to a USB port on a PC for TAS5538 control by software.

If any of these items are missing, contact the nearest Texas Instruments Product Information Center to

inquire about a replacement.

Connect the Input-USB Board 3 to the TAS5612L/14LDDVEVM using the delivered IDC cable.

2.3 Power Supply Setup

2 power supplies are needed to power the TAS5612L-TAS5614LDDVEVM. Voltage and current

requirements for the PVDD power supply are shown in the table below. Connect this power supply to the

EVM using banana cables or wires secured to the power supply binding posts PVDD and GND. A second

power supply, 12Vdc at 500mA, is required to power Input-USB Board 3. Connect the 12V power supply

to the Input-USB Board 3 using banana cables or wires secured to the power supply binding posts +12V

and GND.

CAUTION

NOTE: Applying voltages above specifications in Table 2 can cause permanent

damage to the hardware. Verify polarity of power supply connections before

powering the EVM.

NOTE: The length of the power supply cable must be minimized. Increasing length of PSU cable is

likely to increase distortion for the amplifier at high output levels and low frequencies.

2.4 Speaker Connection

CAUTION

Both positive and negative speaker outputs are floating and cannot be

connected to ground (e.g. through an oscilloscope). To measure a BTL output

connect an oscilloscope probe to each side of the output, connect both ground

clips to EVM ground and use the oscilloscope math functions to show the

difference between the 2 probe signals.
