1.3 Description
The TLV320AIC3110 is a low-power, highly integrated, high-performance codec which supports stereo
audio DAC, and mono audio ADC.
The TLV320AIC3110 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 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 blocks (PRB). 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 TLV320AIC3110 has a programmable digital sine-wave generator and is available in a 32-pin QFN
package.
