Data acquisition is the process of measuring or sampling physical conditions and converting the data into digital form. Analog-to-Digital Converters (ADCs) are an important component of this data acquisition chain. ADCs enable the conversion of an analog voltage, current or temperature signal, into a digital representation of the analog input. The purpose of this article is to provide an overview of the TC3402VQRTR integrated ADC, its application field and working principle.The TC3402VQRTR Integrated ADC is a multifunctional analog-to-digital converter, which combines multiple functions in a single-chip solution. It consists of a low-noise differential input stage with adjustable gain, a 12-bit successive-approximation register (SAR) ADC, and an integrated reference controller in a single package. This 5-port ADC can operate on a single 5 V supply, has an essentially linear transfer function, and its dynamic performance is conditioned by an adjustable-bandwidth output filter.The TC3402VQRTR ADC offers a wide range of operating modes and parameters. The adjustable gain stage offers a range of gains from 1 to 255 with a maximum random gain error of ±0.3%. The ADC has several output port options, including SPI, MDIO, and other digital interface types. It has a settling time of less than 10 us, and operates over a temperature range of -40°C to +85°C.The main application fields of the TC3402VQRTR ADC include data acquisition, telecommunication, process control, industrial automation, and automotive systems. Its features make it suitable for demanding measurement tasks, such as monitoring temperature, pressure and flow, motor speed control, and vibration measurements. In addition, the TC3402VQRTR is also suitable for applications that require precision and accuracy, such as medical instrumentation and instrumentation applications in general.The working principle behind the TC3402VQRTR ADC is fairly simple. The device contains an analog-to-digital converter that is connected to the input signal. The input signal is then amplified and fed to the converter, which then performs analog-to-digital conversion. The output from the converter is a digital signal that is used in the application.In summary, the TC3402VQRTR ADC is a highly integrated, cost-effective solution for a wide range of data acquisition and instrumentation applications. It offers high performance, programmable gain and resolution, fast settling time, and wide temperature range operation in a single package. This makes it ideal for applications that require reliable, high-performance data acquisition.
