7 Detailed Description

7.1 Overview

The TAS5815 device integrates 4 main building blocks together into a single cohesive device that maximizes

sound quality, flexibility, and ease of use. The 4 main building blocks are listed as follows:

1. A stereo Digital to PWM Conversion block.

2. An Audio DSP subsystem.

3. A flexible close-loop amplifier capable of operating in stereo or mono, at several different switching

frequencies, and with a variety of output voltages and loads.

4. An I2C control port for communication with the device

The device requires only two power supplies for proper operation. A DVDD supply is required to power the low

voltage digital circuitry. Another supply, called PVDD, is required to provide power to the output stage of the

audio amplifier. One internal LDO convert PVDD to 5 V for GVDD and AVDD.
