    TAS5631DKD2EVM 3

    1 Overview The TAS5631DKD2EVM PurePath™ HD customer evaluation module demonstrates the integrated circuits TAS5631DKD and TAS5518PAG from Texas Instruments (TI).

    The TAS5631DKD is a high-performance, integrated Stereo Feedback Digital Amplifier Power Stage designed to drive 4 Ohm speakers at up to 300 W per channel. The device incorporates TI’s Equibit™ technology and is designed to be used with TI’s Equibit™ modulators. This system requires only a simple passive demodulation filter to deliver high-quality, high-efficiency audio amplification.

    TAS5518PAG is a high performance 32 bit (24 bit input) multi channel PurePath Digital™ Pulse Width Modulator (PWM) based on Equibit™ technology with fully symmetrical AD modulation scheme. The device also has Digital Audio Processing (DAP) that provides 48 bit signal processing, advanced performance and a high level of system integration. The device has interfaces for headphone output and Power Supply Volume Control (PSVC).

    This EVM is easy configurable to 2 BTL channels for stereo evaluation or 1 PBTL (parallel BTL) channel for subwoofer evaluation.

    This EVM, together with a TI input-USB board 2, is a complete stereo digital audio amplifier system which includes digital input (S/PDIF), analog inputs, interface to PC and DAP features like digital volume control, input and output mixers, automute, tone controls, loudness, EQ filters and dynamic range compression (DRC). There are configuration options for power stage failure protection.

    2 Quick Setup Guide This chapter describes the TAS5631DKD2EVM board in regards to power supplies and system interfaces. The chapter provides information regarding handling and unpacking, absolute operating conditions, and a description of the factory default switch and jumper configuration.

    This chapter provides a step–by–step guide to configuring the TAS5631DKD2EVM for device evaluation.

    2.1 Electrostatic Discharge Warning

    Many of the components on the TAS5631DKD2EVM are susceptible to damage by electrostatic discharge (ESD). Customers are advised to observe proper ESD handling precautions when unpacking and handling the EVM, including the use of a grounded wrist strap at an approved ESD workstation.

    CAUTION

    2.2 Unpacking the EVM

    Upon opening the TAS5631DKD2EVM package, please check to make sure that the following items are included:

    • 1 pc. TAS5631DKD2EVM board using one TAS5518PAG and one TAS5631DKD.

    • 1 pc. TI Input-USB board 2 for interfacing TAS5631DKD2EVM w. SPDIF/analog sources and PC for control.

    • 1 pc. Signal & Control Interface IDC cable for connection to an I2S front-end like the attached TI Input-USB board 2.

    • 1 pc. Cable for connecting Input-USB board 2 to a USB port on a PC for TAS5518 control by software.

    • 1 pc. AC to DC External 15 V Power supply (System supply).

    • 4 pcs. AC Input Clips for External 15 V Power Supply (US, Europe, UK and Australia).

    • 1 pc. PurePath CD-ROM.

    If any of these items are missing, please contact the Texas Instruments Product Information Center nearest you to inquire about a replacement.

    Connect Input-micro board to TAS5631DKD2EVM 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. H-bridge Power supply is connected to the EVM using banana cables. System Power Supply is supplied from the enclosed External 15 V wall plug adapter.

    Caution: Failure to observe ESD handling procedures may result in damage to EVM components.

    CAUTION

    Note:

    The length of power supply cable must be minimized. Increasing length of PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies.

    2.4 Speaker Connection

    CAUTION

    Caution: Applying voltages above the limitations given in table above may cause permanent damage to your hardware

    Caution: Both positive and negative speaker outputs are floating and may not be connected to ground (e.g. through an oscilloscope)

    2.5 Output configuration BTL and PBTL

    When changing mode e.g. from BTL to PBTL make sure that RESET is activated before changing the state of mode switches SW1 and SW2. Switch SW1 and SW2 has to be synchronized in state BTL or PBTL.

    In PBTL mode the load has to be connected according to the figure below:

    Figure 4. TAS5518 GUI window

    From the files menu load the configuration file:

    TAS5631DKD2EVM Configuration (1.00).cfg

    The file is located on the PurePath CD-rom. This file contains all settings for a default setup of the EVM.

    For easy access of the file it is recommended to copy the files into directory where the GUI is installed. Default is C:\Program Files\Texas Instruments Inc\TAS5518\

    For more advanced use of the GUI please refer to GUI User’s Guide and data manual for TAS5518.

    3 Protection This chapter describes the short circuit protection and fault reporting circuitry of the TAS5631 device.

    3.1 Short Circuit Protection and Fault Reporting Circuitry

    The TAS5631 is a self-protecting device that provides fault reporting (including high-temperature protection and short circuit protection). TAS5631 is configured in back-end auto-recovery mode and therefore resets automatically after all errors (M1, M2 and M3 is set low), see datasheet for further explanation. This mean that the device will re-start it self after an error occasion and report shortly through the /SD error signal.

    10 TAS5631DKD2EVM

    3.2 Fault Reporting

    The /OTW and /SD outputs from TAS5631 indicate fault conditions. Please refer to the TAS5631 data manual for a description of these pins.

    Table 3. TAS5631 Warning/error signal decoding /SD /OTW1 /OTW2 Device Condition

    0 0 0 High temperature error and/or high current error 0 0 1 Under voltage lockout or high current error. 100°C temperature warning. 0 1 1 Under voltage lockout or high current error 1 0 0 125°C temperature warning 1 0 1 100°C temperature warning 1 1 1 Normal operation, no errors/warnings

    The shutdown signals will together with the temperature warning signal give chip state information as described in the table above. Device fault reporting outputs are open-drain outputs.
