TLV320DAC3100-Q1 - Low-Power Stereo Audio DAC With Audio Processing

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.

This data manual is designed using PDF document-viewing features that allow quick access to information. For example, performing a global search on "page 0 / register 27" produces all references to this page and register in a list. This makes it easy to traverse the list and find all information related to a page and register. Note that the search string must be of the indicated format. Also, this document includes document hyperlinks to allow the user to find a document reference quickly. To come back to the original page, click the green left arrow near the PDF page number at the bottom of the file. The hot-key for this function is alt-left arrow on the keyboard. Another way to find information quickly is to use the PDF bookmarks.
