description:  the following discussion refers to the schematic below. in operation, approximately 6.3 volts is applied to the noninverting input of the op amp. the voltage is amplified by the op amp to produce a 10.000v output. the gain is determined by the networks r1 and r2: g=1 r2/r1. the 6.3v zener diode is used because it is the most stable diode over time and temperature.   the zener operating current is derived from the regulated output voltage through r3. this feedback arrangement provides a closely regulated zener current. this current determines the slope of the references' voltage vs. temperature function. by trimming the zener current a lower drift over temperature can be achieved. but since the voltage vs. temperature function is nonlinear this compensation technique is not well suited for wide temperature ranges.   thaler corporation has developed a nonlinear compensation network of thermistors and resistors that is used in the vre series voltage references. this proprietary network eliminates most of the nonlinearity in the voltage vs. temperature function. by then adjusting the slope, thaler corporation produces a very stable voltage over wide temperature ranges. this network is less than 2% of the overall network resistance so it has a negligible effect on long term stability. by using highly stable resistors in our network, we produce a voltage reference that also has very good long term stability.
