Switch volume control by op-amp IC

Switch press added – reduced pressure
This circuit IC1 is IC op amp circuit connected to an Integrator circuit. Operation of the circuit. When the press switch S1 will have positive current flow from the power supply Through resistor R1 to charge the capacitor C2. As a result the output of IC1, lower voltage to 0 volts. When the switch press switch S2, the voltage output level of IC1 is back. Increase nearly as quickly or until the supply voltage. When the buffer circuit IC1.Therefore, voltage output of IC1 is how much value will be passed to IC2 and the output voltage (Vout) that you want.

Non – Inverting Amplifier by IC LM741

This is Non – Inverting Amplifier Circuit by IC LM741.
For amplifier signal Frequency low power.

Today we try out Non – Inverting Amplifier circuit by IC LM741. Many you have who to ever study about the integrated circuit op-amp may appear familiar good with this circuit. It basically the base of amplifier circuit. Can induce apply the work has very plentiful from our circuit has can to calculate seek equipment value. By appraise R1 and R2 control the expansion ratio has of the circuit as follows, Vout = Vin(1+ R2/R1) Request friends have fun Non – Inverting Amplifier Circuit by IC LM741, please sir.

Buffer op-amp by IC LM741

The buffer circuit,Used for coupling two circuits togethe, such as the differential family of the IC or transistor that’s not good impedance matching.The op-amp IC objects have the output low impedance and input high impedance. When connected to other circuits, so there is no any effect.The gain is equal to 1 always.Does not to change any signal Vin = Vout.
This circuit is an example of a buffer op-amp circuit, use IC Number 741 performs this function very well, does not require any additional equipment.Signals can be used with any format, but the frequency response up to 1Mhz, and limit the maximum voltage level power supply circuit is about 18V. For volt supply use , +/- 5V-18V.
