PCM1794DBR, a type of high performance audio digital-to-analog converter (DAC), has been widely used in recording and playback applications featuring a sample rate up to 24-bit of 192 kHz. The excellence of this DAC is attributed not just to its high resolution, but also its low output noise, great dynamic range, and the ability to accept a wide range of input format and requirements. This article will explain the application field and how to work principle of it.

Application field

The application field of PCM1794DBR is mainly in the audio industry and controlling system of modern automotive and home audio solutions. In the audio field, PCM1794DBR is used to help recording and playback applications and produce a high degree of fidelity and accuracy in sound. By applying PCM1794DBR to these systems, designers can easily tailor their solutions to meet specific user needs – such as providing touchscreen interfaces, advanced audio processing, and other features that enhance their user experience.

Besides the audio industry, PCM1794DBR is also applied to the various controllers of automotive and home audio solutions, like graphics processor, stereo or surround system controllers, multimedia players, gaming boxes, etc. In these controllers, PCM1794DBR supports different formats and modes of digital audio data and provides a direct connection of high-definition audio data from the digital sources to the audio system.

Working principle

PCM1794DBR is an advanced DAC with a very small form factor and several in-built features for audio signal processing. It mainly works by receiving digital input audio signals from a digital source and converting them into the appropriate analog signal. This is primarily done by using a multi-bit modulation technique, which converts the digital input audio signals into analog signals that can then be easily amplified or sent out to a speaker. After the conversion, the PCM1794DBR then works to reproduce the sound as accurately as possible with its low distortion, low noise, and wide dynamic range.

PCM1794DBR also provides a low level of Total Harmonic Distortion (THD) and Intermodulation Distortion (IMD), which are related to the signal-to-noise ratio (SNR). This helps it to produce cleaner and more accurate results, which can then be amplified according to individual needs. Finally, the converter is also capable of accepting a wide range of digital input formats, from standard stereo and multi-bit formats to DSD and DSD-X.

In conclusion, PCM1794DBR is a powerful and advanced audio converter that has found wide application in both the audio industry and automotive and home audio solutions. This converter offers low output noise, wide dynamic range and can support different formats and modes. The most important feature of this converter is the low level of Total Harmonic Distortion and Intermodulation Distortion, which ensures that the sound that is produced is clear and accurate. With the wide range of features and excellent performance, PCM1794DBR is an ideal choice for audio designers who need to create solutions that can meet specific user needs.
