PCM2906DBRG4 is an audio codec feature to integrate a stereo audio CODEC/DAC system and an S/PDIF digital interface. It can be used as an analog-to-digital converter, digital-to-analog converter, and as an ADC/DAC interface for audio applications. The device is composed of two major functional blocks: a stereo ADC, and a stereo DAC. The PCM2906DBRG4 audio codec device can be used in a wide range of applications, such as audio streaming, audio recording, loudspeaker systems, multimedia, and so on.

The working principle of PCM2906DBRG4 is quite simple. It consists of an ADC (analog-to-digital converter) and a DAC (digital-to-analog converter) connected in series. The PCM2906DBRG4 can convert audio data from analog to digital, as well as digital to analog, with a sample rate of up to 192kHz. Aside from the stereo inputs, there is also a multi-mode input which can accept digital signals from S/PDIF, I2S, TDM, and other digital audio buses. The output can also be selected from either the analog outputs or the S/PDIF digital output, according to the application’s needs.

The analog-to-digital converter of the PCM2906DBRG4 can sample data with 12-bit resolution at up to 96kHz sampling rate, with low distortion and noise. To minimize the potential for aliasing, the device includes a digital audio decimator and has a 500kHz low-pass filter with 93.75dB of stopband attenuation. The DAC part of the device can convert digital audio to analog with a sample rate of up to 192kHz and can provide an output of up to 2Vrms. It also has two independent speaker amplifiers, each able to provide up to 1W into a 16Ω load.

The main application field of the PCM2906DBRG4 is as an audio codec and interface. It can be used as an ADC/DAC and S/PDIF interface in consumer electronics and multimedia devices, such as desktop and laptop computers, digital audio players, set-top boxes, speakers, audio recording equipment, and other audio devices. The PCM2906DBRG4 can also be used for a wide range of audio streaming and recording applications, such as digital audio streaming, sound synthesis, digital audio mixing, and speech recognition.

The PCM2906DBRG4 is an ideal solution for a wide range of audio applications. Its versatile analog and digital IO capabilities, combined with its low distortion, low noise and wide bandwidth, make it suitable for a variety of audio applications. Its ability to sample data up to 192kHz with low distortion and noise makes it especially suitable for audio streaming and recording applications.
