The TLV320AIC3100 is

low-power, highly

integrated, high-performance codec which provides a

stereo audio DAC, a mono audio ADC, and a mono

class-D 4-Ω speaker driver.

The TLV320AIC3100 features a high-performance

audio codec with 24-bit stereo playback and

monaural record functionality. The device integrates

several analog features, such as a microphone

interface, headphone drivers, and speaker drivers.

The TLV320AIC3100 has built-in digital audio

processing blocks (PRB) for both the DAC and ADC

paths. 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 by either pin control or

by register control. The audio functions are controlled

using the I²C serial bus.

• Digital Mixing Capability

• Programmable Digital Audio Processor for

Bass Boost/Treble/EQ With up to Five Biquads

for Record and up to Six Biquads for Playback

• Pin Control or Register Control for Digital-

Playback Volume-Control Settings

• Digital Sine-Wave Generator for Beep

• Integrated PLL Used for Programmable Digital

Audio Processor

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

TDM Audio Interfaces

• I²C Control With Register Auto-Increment

• Full Power-Down Control

• Power Supplies:

– Analog: 2.7 V–3.6 V

– Digital Core: 1.65 V–1.95 V

– Digital I/O: 1.1 V–3.6 V

The TLV320AIC3100 has a programmable digital

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

package.

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

• 5-mm × 5-mm 32-QFN Package
