Installation

Access to control signal gain and data format through EVM-software graphic user interface (GUI)

3Installation

This section describes the software and EVM installation.

3.1Software Installation

Execute the GUI install program setup.exe, found in the TAS570x GUI directory in the provided compact disc. Once the program is installed, the program group and shortcut icon is created in Start Program Texas Instruments Inc TAS570x Interface.

3.2EVM Installation

The following are the basic tools for the initial EVM power up.

5 V, 1 A power supply (VIN)

10–26 V, 4 A power supply (PVDD)

Banana-style test leads for power supplies and speakers

Optical cable for SPDIF interface based on signal source

Coaxial cables with phono plugs for analog audio if digital audio is unavailable

USB cable

EVM software

Two 8-Ωspeakers or loads

The following sections describe the TAS5601EVM board in regards to power supply (PSU) and system interfaces.

3.2.1PSU Interface

The TAS5601EVM module is powered by two power supplies connected to the MC5601 controller board: a 5-V power supply (VIN) and a 10-V to 26-V (PVCC) power supply. The 3.3-V level is generated on the board by a voltage regulator from the 5-V supply.

Note: The power-supply cable length must be minimized. Increasing the length of the PSU cable increases the distortion of the amplifier at high output levels and low frequencies.
