The Texas Instruments TLV320AIC20IPFBR is a highly integrated, low-power, stereo audio Codec designed especially for portable digital audio applications. It contains two channels of audio decode with eight analog-to-digital converters (ADCs), two channels of digital-to-analog converters (DACs) and a digital signal processor (DSP).

The TLV320AIC20IPFBR has a wide variety of features including sample rate for data rates from 8 kHz to 48 kHz, selectable line gain, multi-format audio data compression (MPEG Layer-1, Layer-2 and AAC), stereo headphone driver output and other features that are particularly suitable for portable digital audio applications. As a low-power, low-cost device, it is suitable for consumer applications such as audio players, portable CD players, car stereos and other consumer audio products.

The TLV320AIC20IPFBR operates as an interface between digital data streams, such as audio in digital distribution formats, and consumer audio devices. The Codec can perform audio encoding, decoding, mixing and audio processing functions. It converts analog audio data into digital data and processes the digital data before outputting it to the consumer audio device. In addition, the Codec can receive and process audio data streams, such as those encoded by MP3 or AAC, and converters them into audio analog signals.

The interface between digital data and the Codec is provided by a digital CODEC, which is used to communicate sound and audio data between the digital interface and the consumer audio device. The CODEC contains various types of control and audio filters, and provides various functions including buffering and gain control.

The TLV320AIC20IPFBR provides two separate channels for audio input and output. Each of these channels is linked to one analog-to-digital converter (ADC) and one digital-to-analog converter (DAC). Both the ADCs and DACs are designed to provide low-noise and clean audio performance. The ADCs are capable of sampling up to 48 kHz with 16-bit resolution. The DACs provide 16-bit resolution at 16-bit PCM audio formats and 8-bit resolution when used in MP3 and AAC formats. The ADCs and DACs are controlled by a DSP, which downloads audio data from memory, processes it and then sends it to the codec for conversion.

The DSP core also provides a wide range of audio DSP functions including interpolation, mixing, filtering and dynamic control. The DSP core can process up to two audio channels simultaneously, making it ideal for portable digital audio applications.

The TLV320AIC20IPFBR is designed to provide a high-quality, low-power solution for portable audio applications. It is suitable for a range of applications including audio players, portable CD players, car stereos and other consumer audio products. With its low power consumption and high performance, the TLV320AIC20IPFBR has become an industry-standard solution for portable digital audio applications.
