Data Acquisition (DAQ) systems are becoming increasingly popular, as the need for precise measurements and detailed data acquisition activities increases. Analog to Digital Converters (ADC) are one of the most important components of any DAQ system. The TDA8763M/5/C4,112 is a high-performance dual channel ADC that is widely used in many DAQ systems. This article will discuss the application field and working principle of this ADC.ApplicationsThe TDA8763M/5/C4,112 is often used in applications such as process control, industrial automation, medical and laboratory test equipment, and consumer electronics. This is due to its ability to convert analog signals into digital data with high accuracy and reliability. Additionally, the ADC is designed to work with single and multi-channel systems, making it a great choice for many different types of DAQ systems.The data acquisition process with the TDA8763M/5/C4,112 involves several stages. First, an analog signal is converted into a digital signal by an analog-to-digital converter. Then, a control and data acquisition (CAD) processor (such as the TDA81XX) is used to process the digital data and convert it into useful information. The processor can also store the data in digital memory. The data stored in digital memory can then be transferred and used by other devices or computer systems.The TDA8763M/5/C4,112 is designed with a high sampling rate, which allows for fast data acquisition. The conversion speed of the ADC also enables real-time measurement and analysis of data. Additionally, the ADC has excellent noise immunity, and its accuracy is not affected by power supply fluctuations. Another important feature is its low power consumption, which makes it an ideal choice for battery-powered applications.Working PrincipleThe TDA8763M/5/C4,112 is an 8-bit, dual-channel ADC that features an on-chip delta-sigma modulator and a dual sample-and-hold circuit. The delta-sigma modulator is used to convert the analog signal into a digital signal. The modulator consists of two stages: an integrator and a filter. The integrator stage converts the analog signal into a digital code, which is then filtered by the filter stage. The filtered signal is then converted into an 8-bit output word.The dual sample-and-hold circuit is used to temporarily sample the analog input signal and hold its value so that the ADC can accurately convert the signal into digital data. The sample-and-hold circuit also helps to reduce noise. The ADC also features a reference voltage generator, which adjusts the reference voltage according to the input signal. This helps to ensure the accuracy of the conversion process.ConclusionThe TDA8763M/5/C4,112 provides an integrated and reliable solution for data acquisition systems. Its high sampling rate and low power consumption make it an ideal choice for many applications, such as process control, industrial automation, medical and laboratory test equipment, and consumer electronics. Additionally, its accuracy and noise immunity make it a great choice for sensitive measurements. The working principle of the ADC is based on the conversion of an analog signal into a digital signal using a delta-sigma modulator and a dual sample-and-hold circuit.
