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.
