1.3 Description
The TLV320DAC3100 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 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 has a programmable digital
sine-wave generator and is available in a 32-pin QFN
package.
