1.3 Description
The TLV320AIC3120 is a low-power, highly integrated, high-performance codec which features a mono
audio DAC and mono audio ADC.
The TLV320AIC3120 features a high-performance audio codec with 24-bit mono playback and mono
record functionality. The device integrates several analog features, such as a microphone interface,
headphone drivers, and speaker drivers. The TLV320AIC3120 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 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 TLV320AIC3120 is available in a 32-pin QFN package. PurePath Studio™
