What is the function of IC 741?
The main function of this IC 741 is to do mathematical operations in various circuits. IC 741 op-amp is made from various stages of the transistor which commonly have three stages like differential i/p, a push-pull o/p, and an intermediate gain stage.
What does an integrator op-amp do?
The operational amplifier integrator is an electronic integration circuit. Based on the operational amplifier (op-amp), it performs the mathematical operation of integration with respect to time; that is, its output voltage is proportional to the input voltage integrated over time.
How op-amp can be used as an integrator?
An op-amp amplifier can be used to perform calculus operations such as differentiation and integration, both of which use reactive components like capacitors in the feedback part of the circuit. An integrating circuit is used to perform the mathematical operation integration.
What type of IC is 741?
The 741 Op Amp IC is a monolithic integrated circuit, comprising of a general purpose Operational Amplifier. It was first manufactured by Fairchild semiconductors in the year 1963. The number 741 indicates that this operational amplifier IC has 7 functional pins, 4 pins capable of taking input and 1 output pin.
How many pins are there in 741 IC?
8 pins
The pin diagram of the IC 741 op amp is shown below. It consists of 8 pins where each pin having some functionality which is discussed in the following. Pin 1 is Offset null. Pin 2 is Inverting input terminal.
How many pins are there in IC 741?
What are the important 741 IC terminals?
IC 741 has two terminals (Pin 1 and Pin 5) at input stage for the purpose where we can add external circuits to balance offset voltages. Offset null adjustment usually requires a potentiometer with its slider connected to the negative supply. Pin 4 is for negative power supply and pin 7 is for positive power supply.
