1.3 Description
The TLV320AIC3111 is a low-power, highly
integrated, high-performance codec which provides a
stereo audio DAC and mono audio ADC.
The TLV320AIC3111 features a high-performance
audio codec with 16-bit stereo playback and
monaural record functionality. The device integrates
several analog features, such as a microphone
interface, headphone drivers, and speaker drivers.
The TLV320AIC3111 has a fully programmable
miniDSP 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 by either pin control or
by register control. The audio functions are controlled
using the I²C serial bus.
The TLV320AIC3111 has a programmable beep
generator and is available in a 32-pin QFN package.
