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™
