An ideal resistor value can be determined Figure 14. Precise −1.2 V Reference Configuration through manipulation of Equation 5. Because the ADR512W characteristics resemble those of a Zener diode, the cathode shown in Figure 14 is 1.2 V higher with respect to the anode (V+ with respect to V− on the ADR512W package). Because the cathode of the ADR512W is tied to ground, the anode must be −1.2 V.
