single polarity supply by ic lm741
This is a simple Single polarity (negative to positive polarity) power supply circuit,For education, the work of a series op amplifiers.Since we use the input pin is a pin non inverting, it is an important condition.
the input power must be negative only As a result, the output voltage. However, if the input is positive, it will not delete the output. Because we used the power supply terminal positive and negative only.Or 4 pin connection with the ground.This circuit may be adapted to the negative circuit. Or to converter a negative voltage to positive voltage.
