It is used for certain types of applications such as multi-channel audio, binaural audio, and more. The chip offers a high level of performance for audio applications, and its features and specifications make it suitable for use in a wide range of audio applications.

Applications

The PCM1753DBQR is commonly used in multi-channel audio, where it can be used to capture and output sound with multiple channels. It also provides a wide range of features and functions to enable multi-channel audio applications.

The PCM1753DBQR can also be used for binaural audio, which is audio captured and reproduced in stereo. This is achieved through the chip’s ability to encode and decode digital audio streams with two channels in parallel. The chip also features a binaural-presence algorithm for improved sound quality.

The chip is also commonly used in sound processors and equalizers, where it is used to manipulate and improve sound quality. It can also be used to reduce distortion and interference, as well as improving signal-to-noise ratios.

Working Principle

The PCM1753DBQR uses a combination of analog and digital components to process sound and audio signals. The analog side of the circuit consists of two differential input channels with programmable gain, as well as two output channels for stereo audio. The digital side consists of two analog-to-digital converters, one for each input channel, as well as two digital-to-analog converters, one for each output channel.

The chip also includes a binaural-presence algorithm, which is used to improve sound quality and reduce interference. This algorithm takes advantage of the two-channel ADC and DAC, allowing for encoding and decoding digital audio streams in two channels in parallel. This also allows for sound processing, such as sound equalization and signal-to-noise ratio improvement.

The PCM1753DBQR also features a high-precision internal clock, which can be used to synchronize audio data, ensuring that the input and output of data is precise. The chip is capable of operating at a wide range of sample rates, allowing it to be used in a range of audio applications.
