In this tutorial we can get information related to sensor amplifier, schematic, and noise. This tutorial presents discussion around sensor, output, and equation.
Lots of discussion related to design, circuit, and frequency are presented inside this tutorial. The following are some excerpt from the tutorial:
The factor p1 models the relative position of the wiper as it moves from one end (p1 0) of the potentiometer to the other end (p1 1). The number of values p1 can assume is a function of the num- ber of taps on the potentiometer. The sensor gain is inversely proportional to (1 p1), is pseudo-logarithmic, and varies from less than unity to 31 for a 32tap potentiometer, such as the CAT5114, and to 99 for a 100-tap potentiometer, such as the CAT5113. The voltage, VREF, represents a programmable offset voltage for the signal-conditioning circuit. You can easily implement the reference voltage by using a digitally programmable potentiometer configured as a programmable voltage divider. Is this the best Design Idea in this issue?
