When it comes to intelligence or industrial automation, we tend to react with powerful APPS, flashy human computer interfaces, or high performance master chips... but behind the technologies we see and feel, the role of simulation technology is actually huge, it is like a low-key giant, quietly support the intelligent, automation of these shiny technology applications from scratch, from the base to strong. For the foreseeable future, both intelligentization and Industry 4.0 will put a higher demand on simulation technology. First is high precision, in order to ensure the quality and personal safety of factory automation and Control Automation, the accuracy requirements for analog chips will continue to improve in the future. Secondly, high-speed data acquisition is required. In the process of developing to full automation, factories need 10 or even 100 times data points, so high-speed and real-time signal acquisition is also an essential requirement, the accuracy of the analog chip, especially the analog signal input chip, is required to be higher. In addition, miniaturization is an inevitable trend in the future, so it requires chips to be miniaturized and integrated continuously. With 24-bit bottlenecks and 32-bit adcs, what are the emerging or emerging challenges in analog data acquisition chips and solutions? Texas instruments TI semiconductor division China Analog Business Development Manager Zhu Wenbin, 24-bit ADC analog-to-digital converter in industrial applications have encountered bottlenecks. In Programmable logic controller, for example, the number of ADC bits ranges from 10 to 20, and 24 bits is already the number of bits. But for oil exploration and other customers with high demand for temperature control, they require higher resolution in the whole temperature range, 24 bit is often not enough. Because the chips with high performance-to-price ratio are all 24-bit ADC, many customers first put forward the demand of higher accuracy. In addition, for industrial high-precision balances, applications that require a higher than 24-bit ADC are also required. The 24-bit ADC market is basically saturated, and a breakthrough in its architecture and accuracy is urgently needed. In addition to high precision, the temperature and the long-time stability of the system are required for all kinds of acquisition boards and systems used in industrial field, so the low-temperature drift of IC devices is required. In response to the above market demand, Ti in real-time, high-speed, high-precision and miniaturization of the direction of a comprehensive consideration, introduced ads12621263 two 32-bit increment-add-on Analog-to-digital converter (- ADC) , by combining high resolution, low noise and integrated fault detection, the two devices have successfully solved the problem of not having both the required performance and characteristics in the past when evaluating and selecting devices.
