_10_V_WITH_BOOTSTRAPPED_OPAMP
High-stability Precision Monolithics 0P-07A bipolar-input opamp with ultralow offset voltage provides precise 10 V virtually independent of changes in supply voltage, ambient temperature, and output loading. Choose value of R1 to maintain zener current at exactly 2 mA, using 5 PPM/'C resistor. All resistor values are determined from exact zener voltage Vz, as given by equations alongside circuit.-D.
