In this article, we will explore the application field and working principles of the 741C083471J device in detail.

Overview

The 741C083471J device is a 12-bit, RDC with an integrated precision resistive network of up to 32 resistors. It utilizes a proprietary capacitive continuous-tracking (CCT) technology to provide high resolution, stable-operation and long lifetime performance. The resistive network is designed to convert an input resistance to an analog voltage, which is further converted to a digital output through an analog-to-digital converter (ADC).

The 741C083471J device enables current sensing, voltage sensing, resistance-to-digital conversion, thermistor monitoring, over-temperature detection, over-speed detection, etc. It can also be used in applications such as temperature measurement, speed measurement, position sensing, pressure sensing, force sensing, humidity sensing, and bio-signal sensing. It’s designed with a wide operating temperature range from -40 degrees Celsius to +125 degrees Celsius. The 741C083471J requires minimal power consumption and provides a fast and stable operation.

Application Field

The 741C083471J is well suited for embedded industrial applications. Its wide operating temperature range and low power consumption makes it ideal for applications in the automotive, medical and consumer electronics industry. It can be used in temperature measurement, speed measurement, position sensing, pressure sensing, force sensing, humidity sensing, and bio-signal sensing applications. It can also be used in industrial automation, medical instrumentation, data acquisition systems, bar code readers, robotics, and embedded systems such as avionics and unmanned aerial vehicles (UAVs).

The 741C083471J can provide high accuracy, stability and consistency when measuring resistive values including temperature, force or pressure, enabling reliable and accurate real-time data feedback. Its resistance-to-digital conversion technology allows for precise measurement and control. Its integrated multiple resistors can bring improved efficiency, accuracy, and reliability.

Working Principle

The 741C083471J utilizes its built-in resistive network to convert an input resistance to an output analog voltage. This is done by connecting the input voltage across the resistive network, which is composed of a series of precise metal film resistors. A change in the resistance at the network will cause a change in the output voltage, which can then be measured by an ADC and converted to a digital output.

The 741C083471J device’s CCT technology provides improved accuracy over traditional digital-to-analog converters (DACs). CCT technology continuously calculates and detects the resistive value using an array of capacitance networks, rather than measuring a single value according to the voltage variation. This provides better tracking when measuring a resistance value that is constantly changing.

The 741C083471J device also features a sophisticated compensation loop that helps maintain a high accuracy and consistency even under dynamic process conditions such as temperature variations and aging. The compensation loop utilizes a series of feedback voltage sources which are used to reduce the effect of noise and temperature stability.

Conclusion

The 741C083471J is a high precision, highly efficient resistance-to-digital converter (RDC) with integrated multiple resistors, suitable for industrial applications and a variety of sensing or position determination tasks. It utilizes a CCT technology for improved accuracy, stability, and consistency when measuring resistive values including temperature, force or pressure, enabling reliable and accurate real-time data feedback. Its wide operating temperature range and low power consumption makes it ideal for embedded industrial applications in the automotive, medical and consumer electronics industry.
