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.

Negative to positive voltage Supply with LM741
In sometimes when friends want to modify negative voltage source from the outside is positive voltage. We try to come to see this circuit use op-amp IC LM741, be usable easily and, It can change R1,R2 for fix the expansion ratio has of the circuit with. See the detail in the circuit adds ...
Power supply positive-negative-ground from a single power supply
I like to try different circuits. Using adapters as a power source. Which it has disadvantages be it can not turn on the negative power supply. However, this circuit can supply both positive and negative. This circuit is used IC number NE555 set up to stable multi vibrator.It produces a fr ...
Precision half wave rectifier using op-amp
This circuit provides for right half wave rectification of the input signal. The op-amp IC no-NE5535 is Dual High Slew Rate Op-Amp, it is used for main of this circuit. The input signal have two-phase supply are Fist, positive signals is the gain is 0; And second, negative signals is the gain ...
Dual Rail Power Supply +/- 0 to 15V 1A by LM317,LM337
The dual rail supply which means there are two supply voltages, one positive, one negative, that are adjusted by a common potentiometer such that supply voltages are equal in magnitude. It is capable of supplying up to +/- 15V DC at up to 1A. Two linear regulators are used, an LM317 on th ...
Positive Negative Probe with IC 555
With this circuit you can can check that which dot of the circuit is Positive Volt or Negative Volt which. This cheap circuit uses the a little component is will appropriate apply with an automobile or motorcycle. This circuit works during Voltage between 5-15V. When build volt supply ...
