1.3 Description

The TLV320DAC3100 device is a low-power, highly integrated, high-performance stereo audio DAC with 24-bit

stereo playback and digital audio processing blocks.

The device integrates headphone drivers and speaker drivers. The mono speaker driver can drive loads down to

4 Ω. The TLV320DAC3100 device 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.

The TLV320DAC3100 device has a programmable digital sine-wave generator and is available in a 32-pin VQFN

package.
