CS4351-CZZ/B

The CS4351-CZZ/B is a high-performance, low-noise and low distortion multi-bit sigma-delta (ΔΣ) analogue to digital converter (ADC) which provides a single-channel, stereo audio digital system. Designed for digital audio systems and applications, the CS4351-CZZ/B provides a highly efficient solution for digital audio conversion.

The CS4351-CZZ/B features a 24-bit linear delta-sigma ADC architecture which allows a converging resolution of up to 24 bits. It includes a 128x oversampling rate, allowing the signal to be interpolated to the required sampling rate of up to 48kHz, plus a 32-bit digital signal-processing engine for application-specific digital signal processing (DSP) functions. The CS4351-CZZ/B supports sampling rates up to 192kHz and it also contains a 192 kHz upsampling filter which suppresses aliasing artifacts and reduces distortion.

In addition, the CS4351-CZZ/B provides an integrated high-resolution headphone amplifier, line driver, and headphone driver. It also enables up to five independent audio channels, with two stereo analog inputs, one stereo digital input and one mono digital input. It integrates an output multiplexer which allows seamless switching between different audio sources.

The CS4351-CZZ/B is ideal for digital audio systems such as professional recording devices or consumer audio products. It is also suitable for various digital signal processing applications such as audio signal analyzing, digital processing, spectral filtering, equalization, and effects generation.

The CS4351-CZZ/B is a versatile ADC that can be used in a variety of audio and signal processing applications. It is designed to provide accurate and reliable digital audio data conversion with a minimum amount of external components and noise. The CS4351-CZZ/B is also designed to minimize transients and reduce clock jitter, making it an ideal solution for higher-end audio systems. It is capable of resolving audio signals up to 48 kHz and 192kHz, allowing for high-quality audio playback.

It is also suitable for applications such as noise cancellation, acoustic-echo control, and voice recognition.

The working principle of the CS4351-CZZ/B likes other delta-sigma converter, which one the most commonly used type of audio ADCs. The analogue signal is first converted with an analogue-to-digital converter towards a single-bit data stream. This data stream is usually filtered and then sent to the converter’s digital filter, before being sent to the digital-to-analogue converter (DAC) and outputted as a digital signal.

The CS4351-CZZ/B is designed to provide exceptionally low noise and distortion in audio applications, offering up to 24-bit resolution with 128:1 oversampling. Its architecture includes a 128x oversampling rate and 32-bit digital signal processing (DSP) engine, allowing for higher sampling rates and improved accuracy. Its integrated 5-channel headphone amplifier, plus line driver, and headphone driver automatically detect the type of audio source for the best audio performance.

The CS4351-CZZ/B is an ideal solution for high-performance, low-noise and low distortion audio applications. Its high-accuracy data conversion and filtering capabilities make it suitable for a wide range of applications including professional audio recording, home recording and digital audio processing.
