1 Hardware Overview

The TAS5806MDEVM showcases the latest TI digital input Class-D closed-loop amplifier. The

TAS5806MD is a digital input Class-D audio amplifier with enhanced processing and an integrated

headphone driver. The EVM is used in conjunction with the PurePath Console Motherboard (PPCMB).

The PVDD supply is provided via the TAS5806MDEVM (Figure 1) and is regulated to 5 VDC and 3.3 VDC

on the PPCMB. The PPCMB provides the I2S, I2C, and 3.3 VDC to the TAS5806MDEVM.

Figure 1. TAS5806MDEVM

1.1 Features

The EVM has the following features:

• 96-kHz input sample rate support

• 2.0, mono and 2.1 capable

• Operates in BTL or PBTL

• PurePath Console Motherboard provides flexible input signal routing (USB, SPDIF, and analog)

• Demonstration, evaluation and development environment via the PurePath Console 3 software (GUI)

TAS5806MDEVM User's Guide

1.2 Functions

The TAS5806MDEVM is controlled by the PPCMB. The digital audio data input to the TAS5806MDEVM is

sent from PPCMB and is selectable from USB audio, optical SPDIF, coaxial SPDIF, PSIA (external I2S)

and analog ADC sources.

1.3 Detailed Operations

Upon power-on, the PPCMB uses USB audio input (default). The I2S signals LRCLK, SCLK, SDIN and

MCLK come from the TAS1020B.

foobar2000 or similar non-processing media source can be used to stream audio. The TAS1020B

enumerates as the following device on a Microsoft Windows operating system (OS): USB audio (USB-

AudioEVM), i, and USB Composite Device, see Figure 2.

Hardware Setup

SLAU719–April 2019

TAS5806MDEVM User's Guide

2 Hardware Setup

Use the following steps when setting up the hardware:

Step 1. Connect the PPCMB to the TAS5806MDEVM.

Step 2. Connect speakers to the TAS5806MDEVM.

Step 3. Connect a PSU to the TAS5806MDEVM and turn on the power. 5-V and 3.3-V LEDs (Yellow)

are illuminated. The USB Lock LED (Blue) is also illuminated.

Step 4. Plug in a USB cable from the PC to the PPCMB.

Step 5. If an optical SPDIF source is used, the blue SPDIF clock-locked LED is illuminated.

2.1 I2C Device Addresses

The default I2C addresses on the EVM are set to 0x58 for the top device (U1) and 0x5A for the bottom

one (U2).
