Analog to Digital Converters (ADCs), also known as ADC, are specialized chips used to process analog signals into digital signals. The CDB5364 is an AD converter chip used in a wide variety of applications, from consumer electronics to medical equipment. The general principles of how an ADC operates are relatively simple, though the chip itself is a complex piece of technology. In this article, we’ll discuss the application fields and inner working principle of the CDB5364 converter.

CDB5364 is a high performance integrated analog to digital converter chip, mainly for handling data acquisition in the field of digital audio. It uses a 24bit delta-sigma conversion system in order to achieve highest quality signals. The chip supports some power-saving features, such as ultra-low-power standby mode, and is designed to be integrated into small or medium scale systems. Additionally, it supports output data formats including LSB, MSB and I2S buses for easy compatibility.

The CDB5364 is designed to be used in a variety of applications. It is suitable for consumer audio applications such as digital media players, high-resolution audio playback systems and digital audio processors. In addition, it is also applicable for medical equipment such as ECG and EEG systems, as well as industrial instrumentation and automation systems.

The chip has some key features that help it tone-match with these applications. One of them is extended dynamic range, allowing it to preserve the original audio signal levels even when working with very large signals. It also has low THD+N and excellent harmonic performance, telling how little amount of distortion will be added to the signal during the conversion process. Lastly, its overcurrent and overvoltage protection features ensure extra reliability.

The working principle of the CDB5364 follows the delta-sigma topology of architechture. It starts from the sampling process, where a low-pass filter is used to eliminate unnecessary high-frequency signals, so that higher resolution can be achieved. After that, the signal will be Split Allow Interleave (SAI) filtered by the modulator and converted into binary numbers within a given time period. Finally, the converted digital signal is sent to the DAC and out of the device.

In summary, the CDB5364 is a versatile and feature-packed AD converter designed for various audio applications. Its 24bit resolution provides high-quality audio conversion, while its extended dynamic range and low THD+N help to preserve the original analogue sound source with minimum distortion. Moreover, its ability to support multiple output formats helps to increase the versatility of its use. With all these advantages, the CDB5364 integrates well into any audio processing system.
