The PCM4104PFBR is a low power, dual-channel audio codec designed for specialized applications. The device contains internal digital clock generators, which provide a variety of sampling rates, including 8, 16, 32, and 48 kHz. It allows for a single chip solution for audio capture, playback, and mixing of up to two channels. The PCM4104PFBR has a host of features that make it ideal for a wide range of applications, including professional audio, audio amplifiers, and consumer audio.

In terms of its application field, the PCM4104PFBR is highly versatile. It is frequently used in professional audio applications, such as multi-channel recording and broadcast applications. The integrated clock generators make it ideal for applications that require multiple channels of audio input and output. In addition, the PCM4104PFBR can also be used in consumer audio applications, such as portable media players, gaming consoles, and tablets, where it can provide stereo audio inputs and outputs.

In terms of its working principle, the PCM4104PFBR is based on a delta-sigma modulator. This type of modulator is commonly used in audio applications, since it is capable of maintaining low noise levels while providing high resolution. The PCM4104PFBR contains a total of 2 Delta-Sigma modulators, one for each audio channel. These modulators take an analog input, typically from a microphone, and convert it into a digital output. The modulator is then capable of downsampling the input to a lower sampling rate and out-putting a stream of bits which have been ad -justed for ampli-tude, frequency, and bit depth. The output of the modulator is then transmitted to the operating system of the application, where the data is processed and converted into an audible format.

Overall, the PCM4104PFBR is a highly useful and versatile device. It can be used for a wide range of applications, from professional audio to consumer audio. The integrated Delta-Sigma modulators allow for high resolution recordings and conversions, while the low power operation ensures that the device can be used in a diverse range of applications. As such, the PCM4104PFBR is an invaluable tool for any audio application.
