1.3 Description
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.
