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 TAS5162DDV6EVM2 TAS5162DDV6EVM2 for device evaluation. 2.1 Electrostatic Discharge Warning Many of the components on the TAS5162DDV6EVM2 TAS5162DDV6EVM2 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 Failure to observe ESD handling procedures may result in damage to EVM components. 2.2 Unpacking the EVM Upon opening the TAS5162DDV6EVM2 TAS5162DDV6EVM2 package, check to make sure that the following items are included: · 1 pc. TAS5162DDV6EVM2 TAS5162DDV6EVM2 board using one TAS5518PAG TAS5518PAG and four TAS5162DDV TAS5162DDV. · 1 pc. TI Input-USB board for interfacing TAS5162DDV6EVM2 TAS5162DDV6EVM2 with SPDIF/analog sources and PC for control. · 1 pc. Signal Interface IDC cable for connection to an I2S front-end like the TI Input-USB board. · 1 pc. Control Interface IDC cable for connection to an I2CTM front-end like the TI Input-USB board. · 1 pc Cable for connecting Input-USB board to a USB port on a PC for TAS5518 TAS5518 control by software. · 1 pc.

Increasing length of PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies. Speaker Connection CAUTION Both positive and negative speaker outputs are floating and may not be connected to ground (e.g. through an oscilloscope). 2.5 GUI Software Installation The TAS5518 TAS5518 GUI provides easy control of all registers in the TAS5518 TAS5518. To install the GUI, run setup file from the PurePathTM CD-ROM. After installation, turn on the power supplies and connect the USB cable to the Input-USB board. Start GUI program from windows menu. Start up of GUI will take few seconds. Figure 3.

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 TAS5518\ For more advanced use of the GUI, refer to the GUI User's Guide and data manual for the TAS5518 TAS5518. 3 Protection This chapter describes the short-circuit protection and fault reporting circuitry of the TAS5162 TAS5162 (SLES194 SLES194) device. 3.1 Short Circuit Protection and Fault Reporting Circuitry The TAS5162 TAS5162 is a self-protecting device that provides fault reporting (including high-temperature protection and short-circuit protection). TAS5162 TAS5162 is configured in back-end auto-recovery mode, and therefore, resets automatically after all errors (M1, M2 and M3 is set low), see the data sheet for further explanation. This mean that the device will restart it self after an error occasion and report shortly through the SD error signal. 3.2 Fault Reporting The OTW and SD outputs from TAS5162 TAS5162 indicate fault conditions. See the TAS5162 TAS5162 data manual for a description of these pins. Table 3. TAS5162 TAS5162 Warning/Error Signal Decoding OTW SD Device Condition 0 0 High temperature error and/or high current error 0 1 High temperature warning 1 0 Undervoltage lockout or high current error 1 1 Normal operation, no errors/warnings The temperature warning signals at the TAS5162DDV6EVM2 TAS5162DDV6EVM2 board are wired - or to one temperature warning signal (OTW pin 22 in control interface connector). Shutdown signals are wired-or into one shutdown signal (SD pin 20 in control interface connector). The shutdown signals together with the temperature warning signal give chip state information as described in Table 3. Device fault reporting outputs are open-drain outputs.
