TLV320AIC3100 Low-Power Audio Codec with Audio Processing and Mono Class-D Amplifier

The TLV320AIC3100 is a low-power, highly-integrated, high-performance codec that provides a stereo audio DAC, a mono audio ADC, and a mono Class-D 4-Ω speaker driver.

The TLV320AIC3100 features a high-performance audio codec with 24-bit stereo playback and mono recording capabilities. The device integrates multiple analog functions such as microphone interface, headphone driver, and speaker driver. The TLV320AIC3100 has a built-in digital audio processing block (PRB) and ADC path for DAC. The digital audio data format is programmable and works with popular audio standard protocols (I2S, left/right justified) in master, slave, DSP and TDM modes. Can support bass boost, treble or equalizer programmable digital signal processing module. The on-chip PLL provides the required high-speed clock digital signal processing blocks. Volume can be controlled by pin control or register control. This audio function uses the I control 2C serial bus. The TLV320AIC3100 features a programmable digital sine wave generator in a 32-pin QFN package.
