Stereo Audio DAC 32-Pin VQFN EP T/R

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.
