1.3 Description
The TLV320AIC3110 device is a low-power, highly integrated, high-performance codec that supports
stereo audio DAC, and mono audio ADC.
The TLV320AIC3110 device 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-justified and right-justified) in master, slave, DSP, and TDM
modes. Bass boost, treble, or EQ is supported by the programmable digital-signal processing blocks
(PRB). 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 TLV320AIC3110 device has a programmable digital sine-wave generator and is available in a 32-pin
VQFN package.
