How does an 741 amplifier work?
In an 741 op amp IC pin2 is the input pin and pin6 is the output pin. When the voltage is applied through the pin2 then the output comes from the output pin 6. If the polarity is positive at the input pin2, then the polarity which comes from the output pin6 is negative. So the output is always reverse to the input.
Why IC 741 is not used for high frequency applications?
Why IC 741 is not used for high frequency applications? IC741 has a low slew rate because of the predominance of capacitance present in the circuit at higher frequencies. As frequency increases the output gets distorted due to limited slew rate.
What is the use of pin 8 in IC 741?
Pin 7: +VCC (positive voltage supply). Pin 8: No Connection. The main pins in the 741 op-amp are pin2, pin3 and pin6. In inverting amplifier, a positive voltage is applied to pin2 of the op-amp; we get output as negative voltage through pin 6.
How many terminals are there in op amp IC 741?
It consists of two inputs and two outputs, namely inverting and non inverting terminals. This IC 741 Op Amp is most commonly used in various electrical and electronic circuits.
Can op amp amplify both AC and DC?
An operational amplifier is a very high gain voltage amplifier. It is used to amplify the signals by increasing its magnitude. Op-amps can amplify both DC and AC signals.
What is bandwidth of op amp?
The operational amplifiers bandwidth is the frequency range over which the voltage gain of the amplifier is above 70.7% or -3dB (where 0dB is the maximum) of its maximum output value as shown below.
What is the drawback of IC 741?
Answer: The drawback of IC 741 is its low slew rate (0.5v/µs), which limits its use in relatively high frequency applications, especially in oscillators, comparators and filters.
What is meant by zero crossing detector?
A zero-crossing detector or ZCD is one type of voltage comparator, used to detect a sine waveform transition from positive and negative, that coincides when the i/p crosses the zero voltage condition. The applications of the Zero Crossing Detector are phase meter and time marker generator.
What is bandwidth of an amplifier?
The Bandwidth (BW) of an amplifier is defined as the difference between the frequency limits of the amplifier. The range of frequencies within a band is known as bandwidth. An amplifier also known as an amp is an electronic device that enhances the power of a signal.

What are the characteristics of the 741 IC?
The 741 IC is developed using the planar epitaxial process (Refer:- Epitaxial Devices – Characteristics ). The IC is made ideal for use as integrator, summing amplifier, voltage follower and other basic applications. The 741 IC is available in the market as 8-pin metal can, 10-pin flat pack, 8 or 14 pin DIP.
What kind of amplifier is IC 741 op amp?
What is IC 741 Op Amp? The term operational amplifier is the full form of an op-amp and it is one kind of IC (integrated circuits). An op-amp is a DC-coupled high gain voltage amplifier with a differential i/p and a single o/p.
Which is the i / p pin in an IC 741?
A=-Rf/R1 In an op-amp 741 IC pin3 is the i/p pin and pin6 is the o/p pin. When the voltage is applied through the pin3 then the output comes from the output pin 6. If the polarity is positive at the input pin3, then the polarity which comes from the output pin6 is also positive.
What is the maximum input offset current for 741 IC?
The maximum input offset current value for 741 IC is 200nA. This value decreases as the matching between the two input terminals is improved and may reduce down to almost 6nA. 3. Input Bis Current Input bias current is the average value of the inverting and non-inverting current.
