AD2S80ATD is a special purpose data acquisition device designed to convert successive angles into a proportional voltage or current. It is a complete magnetic angle-to-digital position converter that provides a high accuracy sinusoidal input waveform that is proportional to the accurate angle of a rotating target shaft. The device can measure angles up to 10,000 revs with relative error values of less than 0.01%.
The AD2S80ATD is specifically designed for applications where two electrical waveforms are required to represent a rotational angle, such as motor control, robotics, and instrumentation. It is ideal for applications such as shaft encoder feedback, steering systems, and robotic control since it converts angular positions into accurate voltage or current waveforms over a wide range of speeds and positions. The applications include motor control, robotics, and instrumentation.
Working Principle
The AD2S80ATD operates on the principle of dual phase sinusoidal waveform regeneration. The device uses a precision Hall effect Angle Transducer to detect the absolute angle of a rotating target shaft. It then samples this analog signal, converts it into a digital form, and uses a digital sine-cosine-to-amplitude conversion algorithm to generate a pair of pure sinusoidal waveforms which are proportional to the measured absolute angle. This data can then be used to accurately determine and control position and speed in a variety of applications.
The AD2S80ATD digitally compensates for various errors in the angle measurements resulting from mechanical misalignments, linearity errors, vibration, and temperature changes. This eliminates the need for manual adjustment and maintenance, and provides a repeatable accuracy of 0.01% over the entire operating temperature range. The device also features an adjustable offset up to 50%.
Benefits and Advantages
The AD2S80ATD offers advantages over other angle-to-digital position converters due to its accuracy, high performance, and low power consumption. The device can sample angles from 0° to 360° with a resolution up to 0.0035°, which is suitable for most applications. The device can also measure angles up to 10,000 revs with relative error values of less than 0.01%. Additionally, the unit offers low power consumption, typically under 1W when both outputs are used, and operates within a wide temperature range of -40°C to +85°C.
The AD2S80ATD is also easy to use and boasts a fast response time. The device is compatible with a variety of different interfaces, including USART, CANbus, SPI, and I2C, and can be easily integrated into existing systems. Additionally, the device has an adjustable deadband (2 to 120°, depending on resolution) to reduce jitter and improve accuracy.
Conclusion
The AD2S80ATD is a special purpose data acquisition device designed to convert successive angles into a proportional voltage or current. It is ideal for applications such as motor control, robotics, instrumentation, and shaft encoder feedback. The device features adjustable offset, low power consumption, fast response time and wide temperature range, as well as advanced digital calibration algorithms to reduce sensitivity to temperature, drift and vibration effects. The device is easy to integrate into existing systems thanks to its compatibility with a variety of different interfaces and its adjustable deadband. Overall, the AD2S80ATD is an excellent choice for accurate motor control, robotics, and instrumentation applications.
