Summary of Contents for Texas Instruments TAS5706EVM2

  • Page 1: Table Of Contents

    This manual describes the operation of the TAS5706EVM2 to evaluate the performance of the TAS5706A. This main contents of this document are: • Details on how to properly connect a TAS5706A Evaluation Module (TAS5706EVM2) and the details of the EVM.
  • Page 2: Overview

    ..................Bill of Materials for TAS5706EVM2 Overview The TAS5706A evaluation module (TAS5706EVM2) demonstrates the TAS5706A device from Texas Instruments. The TAS5706A combines a high-performance PWM processor with a class-D audio power amplifier. This EVM can be configured with two bridge-tied loads (BTL) (2.0) or two single-ended (SE) and one BTL sub (2.1) or four SE (4.0) modes.
  • Page 3: Tas5706Evm2 Printed-Circuit Board

    Figure 1. TAS5706EVM2 Printed-Circuit Board The TAS5706EVM2, together with other TI components on this board, is a complete 2.1-channel digital audio amplifier system. The MC57XXPSIA Controller board includes a USB interface, a digital input (SPDIF), analog inputs via the ADC (PCM1808), power inputs and other features like a mute function and power down.

    2.1.1 Connecting the TAS5706EVM2 to MC57xxPSIA On the right side of the MC57xxPSIA is a terminal block and another on the left of the TAS5706EVM2 (labeled J1). Carefully place the MC57xxPSIA block above the TAS5706EVM2 block and gently push down.
  • Page 6: Connecting Tas5706Evm2 To Mc57Xxpsia

    2.1.2 PSU Interface The TAS5706EVM2 is powered by two power supplies connected to the MC57xx 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.
  • Page 7: Btl Connection

    When connecting a speaker in BTL mode, connect the speaker’s two terminals (“+” and “-“) across two outputs on the TAS5706EVM2. Ensure that the jumper (JP1 - JP4) on each output is in place. When connecting a speaker in Single-Ended (SE) mode, connect the speaker’s “+” terminal to one EVM output, and the speaker’s “–“...

    MC57xxPSIA board facilitates the connection between a host computer and the device. The EVM USB circuit is powered by the 5-V USB line of the host PC and is independent of the power supplies available on the board. The USB device that is used is a TAS1020B from Texas Instruments. 2.1.5...
  • Page 9: Software Installation

    2.1.7 Board Power Up General Guidelines Connect the MC-57xx and the TAS5706EVM2 boards by locating pin 1 on each board, indicated by a small white triangle. The MC-57xx plugs down onto the TAS5706EVM2 board (i.e., the TAS5706EVM2 board fits underneath the MC57xxPSIA board). Pin 1 on each board must be connected to each other.
