The AD2S82ALPZ is a synchronous, absolute angle position converter. It is capable of resolving up to 14 bits of absolute angular information within a single turn. Its performance is typically limited to a 2500 to 5000 PPR count range and it is able to track transition points as well as operate in a wrap-around mode. This is useful in situations where non-linear or non-standard applications are required and the device is capable of performing both linear and non-linear operation.

Given its high resolution and accuracy, the AD2S82ALPZ is ideally suited for applications with more demanding requirements. Examples include navigation, motion control, robotics, medical and factory automation, precision testing and measurement, and semiconductor manufacturing equipment. The device’s versatility also makes it suitable for military, marine and aviation applications.

The AD2S82ALPZ is comprised of a transducer, analog front-end and digital signal processing circuitry. The transducer can be either a differential LVDT (Linear Variable Differential Transducer), Sin/Cos sensor, or a Resolver. An LVDT works by converting a mechanical displacement into an electrical signal by varying the device’s core position with respect to the two differential windings. This creates an AC signal that is amplified and then rectified to provide a DC signal.

The analog front-end includes a signal conditioning circuit to match the transducer’s output signal with the device’s input requirements. This includes a gain setting and an adjustable zero-offset calibration option. The AD2S82ALPZ also includes a low-pass filter to reduce high frequency noise in the signal. The signal is then processed by a sigma-delta analog-to-digital converter, which provides up to 14-bits of resolution. Finally, the signal is then encoded and transmitted out of the device.

The AD2S82ALPZ provides a high degree of accuracy, precision and reliability. It offers resolution of up to 14-bits, reproducibility of plus or minus 1 count, and update rate of 50 Hz. It also has a wide operating temperature range from -40 Degrees Celsius to +105 Degrees Celsius and an industry-leading linearity specification of +/- 0.1%.

In conclusion, the AD2S82ALPZ is ideal for a wide range of applications requiring accurate and reliable angular position feedback. Its high resolution and precision, combined with a wide operating temperature range, makes it suitable for a wide range of environments and applications.
