The Non-C-XX-SIN is a microprocessor controlled Square Root Extractor. It has an adjustable drop out setting which defines the lower limit of the output at which the square root extraction ceases. This feature is important especially in environments where signals are noisy since low input signals produce large results after the square root function.

For example, an input of 1% translates into an output of 10%. Therefore, if the input fluctuates by approximately 1% in the lower (4-5 mA) region, the output may vary by more than 10%. By setting the drop out to a few percent above 10% output, the actual output will remain at 4 mA untill the true output rises above the drop out setting.
