1.3 Description
The TLV320DAC3100-Q1 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 drives loads down to 4
Ω. The TLV320DAC3100-Q1 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 and right-justified) in
master, slave, DSP, and TDM modes. Bass boost, treble, or EQ is supported by the programmable digital signal-
processing block. An on-chip PLL provides the high-speed clock required by the digital signal-processing block.
The volume level is controlled either by pin control or by register control. The audio functions are controlled using
the I²C serial bus.
The TLV320DAC3100-Q1 has a programmable digital sine-wave generator and is available in a 32-pin QFN
package.
