The TLV320AIC3100IRHBT is a Low-power Audio Codec with audio processing and mono class-D amplifier. It features a high-performance audio codec with 24-bit stereo playback and monaural record functionality. The device integrates several analogue 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. It has programmable digital audio processor for bass boost/treble/EQ with up to five biquads for record and up to six biquads for playback.
