Description. A simple circuit for converting a floating dual power supply is shown here.The circuit is based on auA 741 op-amp. The input supply is splitted by the voltage divider circuit formed of R1 & R2 ,and given to the non-inverting input of the IC1. The output (Pin 6) is conn...
Schmitt Trigger Circuit Using Op-Amp uA741 IC As shown in the circuit diagram, a voltage divider with resistors Rdiv1 and Rdiv2 is set in the positive feedback of the 741 IC op-amp. The same values of Rdiv1 and Rdiv2 are used to get the resistance value Rpar = Rdiv1||Rdiv2 ...
First, let’s convert the idea from above into a more easy block diagram. PIR motion sensor alarm circuit block diagram Thisblock diagramis not too difficult, and we can use it as a broad process-by-process guideline for our circuit design. The12V Sirenis an alarm-sounding device. It is...
In this Wireless Switch Circuit, LM741 is used to provide the Low to high Clock pulse to IC 4017, for each time when one passes a hand over the LDR. Learn more about Op-amp 741 here. Pin diagram of LM741 Pin Configuration of LM741 PIN NO. PIN Description 1 Offset null 2 ...

A very neat and reasonably efficient 5 band graphic equalizer circuit using only passive components can e built as shown in the following diagram: As can be seen in the figure above, the 5 band equalizer has five potentiometers for controlling the tone of the input music signal, while the ...
Thank you so much for your reply and corrected circuit diagram. Now that you have switched the LDR and resistors around it makes sense. However, I plucked the two resistor values out of the air. I don’t know if they will allow the MOSFET to fully saturate when switched on at dusk. ...
Other Parts Discussed in Thread:LM741 Hello I am looking for a diagram showing the transistor configuration/details of the input stages of the device. Basically something similar to what is shown in the Functional Block Diagram of the LM741 datasheet. ...
