The AD2S82AKPZ-REEL is an integrated sinusoidal-to-digital converter designed for use in high-performance closed-loop servo systems. It is part of the AD2S82 series of ICs produced by Analog Devices, Inc.

The AD2S82AKPZ-REEL is specifically designed to provide precision position sensing capabilities to servo motors, with a linearity of 0.005°, and a resolution of 5.941µs. It is ideal for use in applications such as robotics, motor control and precision instrumentation. In addition, its high-speed sampling and digital output provides for fast and accurate position logging.

At its core, the AD2S82AKPZ-REEL uses a synchronous, zero latency sigma-delta converter to convert a continuous sinusoidal signal into a digital signal. This signal is then sent to the on-board Digital Signal Processor (DSP) where it is further processed and converted into a standard format.

The basic operation of the AD2S82AKPZ-REEL consists of a few simple steps. First, the incoming sinusoidal signal is sampled at a certain frequency, and its magnitude is then quantified. Next, the DSP performs a digital filtering process on the signal, where it is differentiated twice and then passed through a band-pass filter. This filtered signal is then fed into an analog-to-digital (A/D) converter, where it is digitized and then converted into a standard format. Finally, from this format, the output is used to determine the position of the servo.

In order to increase accuracy, the AD2S82AKPZ-REEL also incorporates a variety of features, such as Autoscale and Adaptive Parameter Adjustment (APA). Autoscale enables the converter to automatically scale the incoming signal based on its magnitude and frequency, while APA adjusts the parameters of the digital filter according to the input signal. This ensures that the converter is able to achieve the best possible accuracy regardless of the input signal conditions.

The AD2S82AKPZ-REEL is a highly accurate and reliable device, making it an ideal solution for high-performance servo systems. Its high accuracy and low latency make it well suited for applications such as robotics, motor control and precision instrumentation, where precision is essential. In addition, its versatility enables it to be used in a wide variety of applications, making it a versatile and reliable solution.
