3 Introduction Introduction The TAS6PHDEVM PurePath Premier Pro customer evaluation module demonstrates the integrated circuits TAS6PHD and TAS8PAG from Texas Instruments (TI). The TAS6PHD is a high-performance, integrated Stereo Feedback Digital Amplifier Power Stage designed to drive -Ω speakers at up to 00 W per channel. The device incorporates the TI Equibit technology and is designed to be used with TI s Equibit modulators. This system only requires a passive demodulation filter to deliver a efficiency, quality audio amplification. TAS8PAG is a high performance bit ( 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 8 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 configurable to BTL channels for stereo evaluation or PBTL (parallel BTL) channel for subwoofer evaluation. This EVM, together with a TI input-usb board, 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. Table.

If any of these items are missing, contact the nearest Texas Instruments Product Information Center to inquire about a replacement. Connect the Input-micro board to the TAS6PHDEVM using the delivered IDC cable.. 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 V wall plug adapter. Table. Recommended Supply Voltages Description Voltage Range Current Requirements Cable Output stage power supply 0 V 6 A J (marked +0V) CAUTION Applying voltages above the specifications given in Table can cause permenant damage to the hardware. 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.. Speaker Connection CAUTION Both positive and negative speaker outputs are floating and cannot be connected to ground (e.g. through an oscilloscope).. 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 SW and SW. Switch SW and SW has to be synchronized in state BTL or PBTL. In PBTL mode the load has to be connected according to Figure : 6 TAS6PHDEVM SLOU7A December 009 Revised May 00 Copyright , Texas Instruments Incorporated

FCC Warning This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may be required to correct this interference. EVM Warnings and Restrictions It is important to operate this EVM within the input voltage range of 0 V to 0 V and the output voltage range of 0 V to 0 V. Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 90 C. The EVM is designed to operate properly with certain components above C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
