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 (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 TLV320AIC3100 has a programmable digital
sine-wave generator and is available in a 32-pin QFN
package.
