Dual Polarity Output Voltage Source Circuit of LM199

Published:2011/7/24 8:21:00 Author:Michel | Keyword: Output Voltage, Source Circuit | From:SeekIC

Dual polarity output benchmark voltage source circuit is as above.It outputs the benchmark voltage which is from negative to positive voltage.The LM199 heater is connected to ±15V power supply.RP1 is ten laps line potentiometer which alters its value to make the output change between +Uz~-Uz.Uz is the stability voltage in LM199 voltage regulating tube. A1 chooses LM1O8A operational amplifier and when it outputs positive voltage.A1 working condition is the same phase amplifier and A1 working condition is the inverse phase amplifier when it outputs inverse voltage.
