Overview
The TLV320AIC3120IRHBR, produced by Texas Instruments, is a low-power, highly integrated, high-performance audio codec. This device features a mono audio DAC (Digital-to-Analog Converter) and a mono audio ADC (Analog-to-Digital Converter), both of which are designed to provide high-quality audio processing. The TLV320AIC3120 integrates several analog features, including a microphone interface, headphone drivers, and speaker drivers. It also includes a fully programmable miniDSP for advanced digital audio processing and supports various audio standard protocols such as I2S, left-justified, right-justified, DSP, and TDM modes. The device is controlled via the I2C serial bus and is available in a 32-pin VQFN package.
