# Basic Operational Amplifier using ic 741

From advances in the manufacture of an integrated circuit. Circuits of the op-amp, can be total production on tiny silicon sheets. That is packaged in a plastic DIP 8-pin, IC op amp is the number of Fairchild, Since the year 1965.

And the op-amp IC is number 741 in the second year. Fri 1968 By the op-amp 741 is still popular today, The price of the op-amp circuits, as well as a single transistor.

Features of ideal op-amp

 Ideal OP-Amp IC-741 1. Voltage gain AOL ? 200,000 V/V 2. Output impedance Ro 0 75? 3. Input impedance Ri ? 2 M? 4. Bandwidth BW ? 1 MHz

I collect that the IC-741 Circuits amplifier is the main equipment. For use in various applications, In different ways.

# Clipping Amplifier Circuit

When an amplifier is overdrive output waveform of voltage and current distortion. it is limit size value.
This is Clipping Amplifier Circuit using LM741 popular op-amp IC. It is basic clipping amplifier,If input is sine wave to distorted square wave type waveform. Vout = -Vin(R2/R1) But the Vout not up to Vz+0.7V
D1 and D2 be zener diode if use 6V values have already the pressure output not exceed +/- 6.7V.

# Inverting Amplifier by IC LM741

Friends at study about the integrated circuit op-amp may nobody that strange Inverting Amplifier by IC LM741. Today we come to see this circuit again. Reserve will valuable in applying work other circuit. Get in the future by we fix R1 and R2. As a result will seek the value Vout get from a formula. Vout = -Vin(R2/R1) As a result request friends jubilantly with using integrated circuit LM741 please sir.

# Non â€“ 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.

# Summing Amplifier by LM741

The summing amplifier is a handy circuit. It are a type of operational amplifier circuit and an inverting amplifier mode. You can add several voltages input together. More than two inputs can be used.
In circuit:
Vout = -R4 ((Vin1/R1) + (Vin2/R2))
When R1 = R2 .
Vout = – R4/R1 (Vin1+Vin2)
When R1=R2=R4 .
Vout = – Vin1 + Vin2

We seen the information in http://en.wikipedia.org/wiki/Summing_amplifier#Summing_amplifier .

An audio mixer circuit is another good example of the summing sounds from different channels together, before send the combined signal to next an amplifier circuit.

# Basic Integrator by LM741

This is the basic integrator circuit used IC op-amp 741 is important part. The follow by range of input into the R1 is Element Input and the C1 is feed back element. This circuit has a different form differentiator circuit. The relationship of the incoming signal frequency, has the effect of changes in voltage output as well, so increased in parallel with R2 to control C1 (Low Frequency Resistor) when the frequency changes.When the frequency changes, and increased leg R3 Non-Inverting. To reduce the voltage Voi.
