1.3 Description

The TLV320DAC3101 is a low-power, highly integrated, high-performance DAC with selectable digital

audio processing blocks and 24-bit stereo playback.

The device integrates headphone drivers and speaker drivers. The TLV320DAC3101 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 by either pin control or by register control. The audio functions are controlled using the I²C serial

bus.

The TLV320DAC3101 has a programmable digital sine-wave generator and is available in a 32-pin QFN

package.
