SLAS671A –FEBRUARY 2010–REVISED MAY 2012

Low-Power Stereo Audio DAC With Audio Processing

and Mono Class-D Speaker Amplifier

Check for Samples: TLV320DAC3100

1 INTRODUCTION

1.1 Features

1.2 Applications

1234

• Stereo Audio DAC with 95-dB SNR

•

Portable Audio Devices

Mobile Internet Devices

eBooks

• Supports 8-kHz to 192-kHz Sample Rates

• Mono Class-D BTL Speaker Driver (2.5 W Into

4-Ω or 1.6 W Into 8-Ω)

• Two Single-Ended Inputs With Mixing and

Output Level Control

1.3 Description

• Stereo Headphone/Lineout and Mono Class-D

Speaker Outputs Available

• Microphone Bias

The TLV320DAC3100 is

low-power, highly

integrated, high-performance stereo audio DAC with

24-bit stereo playback and digital audio processing

blocks.

• Headphone Detection

• 25 Built-in Digital Audio Processing Blocks

(PRB_P1 – PRB_P25) Providing Biquad and FIR

Filters, DRC, and 3-D Structures

• Digital Mixing Capability

• Pin Control or Register Control for Digital-

Playback Volume-Control Settings

The device integrates headphone drivers and

speaker drivers. The mono speaker driver can drive

loads down to 4 Ω. The TLV320DAC3100 has a suite

of built-in processing blocks for digital audio

processing. The digital audio data format is

programmable to work with popular audio standard

protocols (I²S, left/right-justified) in master, slave,

DSP, and TDM modes. Bass boost, treble, or EQ can

be supported by the programmable digital signal-

processing block. An on-chip PLL provides the high-

speed clock needed by the digital signal-processing

block. The volume level can be controlled either by

pin control or by register control. The audio functions

are controlled using the I²C serial bus.

• Digital Sine-Wave Generator for Beeps and Key

Clicks (PRB_P25)

• Programmable PLL for Flexible Clock

Generation

• I²S, Left-Justified, Right-Justified, DSP, and

TDM Audio Interfaces

• I²C™ Control With Register Auto-Increment

• Full Power-Down Control

• Power Supplies:

The TLV320DAC3100 has a programmable digital

sine-wave generator and is available in a 32-pin QFN

package.

– Analog: 2.7 V–3.6 V

– Digital Core: 1.65 V–1.95 V

– Digital I/O: 1.1 V–3.6 V

TEXT ADDED FOR ALIGNMENT

– Class-D: 2.7 V–5.5 V (SPKVDD ≥ AVDD)

• 5-mm × 5-mm 32-QFN Package
