Evaluation and demonstration boards and kits are designed to help researchers, developers, and engineers test, evaluate, and demonstrate the features of different components, especially microprocessors and complex integrated circuits such as microcontrollers, memories, A/D converters, and other digital electronics. This article will discuss the EVAL-AD2S1210SDZ application field and working principle.

Applications

The EVAL-AD2S1210SDZ is an evaluation and demonstration board and kit produced by Analog Devices, Inc. It is specifically designed for easier evaluation of the resolution, dynamic performance, programming, and error calibration features of the AD2S1210 dual-time-constant resolver-to-digital converter (RDC). The board contains two RDCs, which allows it to be used to equip both large and small motors.

The EVAL-AD2S1210SDZ can be used for numerous types of machines in motion control applications such as robotics, machine tools, and automated assembly lines. It is suitable for applications ranging from automotive to the process control industry. Additionally, its wide power supply range makes it suitable for industrial and consumer applications, as well as application testing.

Working Principle

The EVAL-AD2S1210SDZ evaluation and demonstration board and kit is powered by a dual-time-constant resolver-to-digital converter. This RDC is a high-accuracy, low-power, and low-noise analog-to-digital converter with digital error calibration. It converts the resolver’s incremental sine and cosine signals into a digital representation of absolute angle, as well as angular rate information.

To ensure that the available analog resolver signal is digitized properly, the relative angle in degrees must be constant. The RDC’s dual-time-constant architecture stabilizes the peak angle of the sine and cosine signals to facilitate the accurate conversion of analog signals into digital ones. The circuit has two separate calibration registers, which are set-up individually for the input range and dead zone. It also contains a delta register, for the angle trim adjustment.

The EVAL-AD2S1210SDZ board includes two analog front-end RDCs, as well as onboard isolated DC supplies. An external isolator is provided to connect the PC with the board’s digital bus. The board also contains a built-in LCD display which is used to monitor the system parameters, as well as analyze the dynamic performance of the RDCs.

Conclusion

In conclusion, the EVAL-AD2S1210SDZ evaluation and demonstration board and kit is a powerful and comprehensive tool for evaluating and demonstrating the features of resolver-to-digital converters. It can be used for numerous types of machines, in motion control applications such as automotive and the process control industry. Its dual-time-constant architecture ensures that the peak angle of the sine and cosine signals is stabilized for accurate conversion into digital signals. Additionally, the board contains a built-in LCD display for monitoring system parameters and analyzing the dynamic performance of the RDCs.
