The AD2S1210WDSTZ is a special-purpose device that enables the conversion of continuous-time signals into a digital form, making it possible to provide both the control and data acquisition applications that require low cost, high-performance capabilities.

The AD2S1210WDSTZ utilizes an R-2R ladder network architecture that enables conversion of both relative and absolute position signals into a 16-bit resolution digital signal. The device is designed to detect resolution down to 0.0003% over the range of 15 ppm total error and over the entire range of the signal. This resolution is achieved even when wide position signals are used. The main benefit of this technology is that it offers a lower cost alternative to other data conversion solutions which require more complex circuitry. While minimizing cost, the AD2S1210WDSTZ still provides the high performance required for reliable and precise operation.

Working Principle

The AD2S1210WDSTZ works by combining incremental optics, variable currents and a digital processing approach. The variable current sources are modulated by the signal to be measured and the incremental optical encoder outputs the time-varying signal. The modulated current is then converted into a digital signal via an R-2R ladder network. The digital signal is then processed by the AD2S1210WDSTZ by using a rail-to-rail comparator and an averaging filter. The output is a 16-bit digital word proportional to the absolute position of the signal.

Application Field

The AD2S1210WDSTZ can be used for a wide range of applications, including but not limited to:

• Degrees of freedom controllers, such as robotics and motion control;
• Position sensor applications;
• Measurement of angular position, linear position and tilt;
