The TLV320AIC3120 device is a low-power, highly integrated, high-performance codec which features a mono audio DAC and mono audio ADC.

The TLV320AIC3120 device 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 device 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-justified and right-justified) in master, slave, DSP, and TDM modes. Bass boost, treble, or EQ are 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 is controlled either by pin control or by register control. The audio functions are controlled using the I²C serial bus.

The TLV320AIC3120 device is available in a 32-pin VQFN package.
