1.3 Description
The TLV320AIC3100 is a low-power, highly integrated, high-performance codec which provides a stereo audio
DAC, a mono audio ADC, and a mono class-D 4-Ω speaker driver.
The TLV320AIC3100 features a high-performance audio codec with 24-bit stereo playback and monaural record
functionality. The device integrates several analog features, such as a microphone interface, headphone drivers,
and speaker drivers. The TLV320AIC3100 has built-in digital audio processing blocks (PRB) for both the DAC
and ADC paths. The digital audio data format is programmable to work with popular audio standard protocols
(I
2
S, 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 I
2
C serial bus.
The TLV320AIC3100 has a programmable digital sine-wave generator and is available in a 32-pin QFN package.
