A. The maximum input voltage of 10V. OP amplifier A, to give ten of 10V reference voltage, and its stability is mainly determined by the Zener diode characteristics, mining com

mission temperature compensated zener diode (IS2192). Zener voltage Vz if the error can be used to adjust the variable resistor, it is IO. oov. s resistor divider circuit (R4vR,) to switch A, input voltage, ul/2 office units in descending order. When you need to 1 voltage accuracy over time, EU resistance must choose a small difference in disrespect of the product ( 0.5 ~ .10 {). OP/Ze buffer amplifier 4. The amplifier, save magnification is 1, is positive to put large, but with sleep} line inverting amplifier, the output voltage into a negative voltage inverter output voltage. - said that the resistance r, four errors on a variable resistor r z mouth into line correction, accurate voltage can be obtained.
