741 ic

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.

Why do we use IC 741 in opamp?

IC 741 mainly performs mathematical operations like addition, subtraction, division, multiplication, integration, differentiation etc. IC 741 has three stages such as differential input, gain, and push-pull output. Pin 1 and 5 are “offset null” or “balance” terminals. The op amp is nothing but a differential amplifier.

Why is it called IC 741?

The number 741 in the name indicates that there are 7 active pins, 4 pins (pin 2,3,4,7) are capable of taking input and 1 pin ( pin 6) is an output pin. The triangular form in the IC represents an op-amp integrated circuit.

What is the value of IC 741?

The typical value for 741 IC is 1.4pF. The op-amp has pins 1 and 5 marked as offset null to determine the offset voltage adjustment range.

How many pins are in LM741?

LM741 has eight pins. The first and fifth pins are the offset and null pins used to balance the input voltage and remove the offset voltage. The second pin is the inverting signal input, while the third one is the non inverting signal input.

How is IC 741 tested?

Testing a 741 IC A voltage is applied to pin3 of the op-amp through the variable resistor (10K). All we need to do is to verify whether the voltages V1 and V2 are exactly same or not. Check them using a multi-meter.

Why it is called op-amp?

An operational amplifier (op-amp) is an integrated circuit (IC) that amplifies the difference in voltage between two inputs. It is so named because it can be configured to perform arithmetic operations.

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 are pins 2 and 3 called in IC 741 opamp?

The representation of 741 IC op-amp comprises eight pins. The most significant pins are 2,3 and 6, where pin 2 and 3 are pin 2 and 3 denote inverting and non-inverting terminals and pin6denotes output voltage.

What are the features of IC 741?

Who invented IC 741?

Sourced by many manufacturers, and in multiple similar products, an example of a bipolar transistor operational amplifier is the 741 integrated circuit designed in 1968 by David Fullagar at Fairchild Semiconductor after Bob Widlar's LM301 integrated circuit design.

What is the pin configuration of op amp IC 741?

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.

What is supply voltage of IC 741?

Supply-voltage operating range for the 741 is +4.5 volts (minimum) to +18 volts (maximum), and it is specified for operation between +5 and +15 Vdc.

Who invented op-amp?

In 1963, a 26-year-old engineer named Robert Widlar designed the first monolithic op-amp integrated circuit, the μA702, at Fairchild Semiconductor.

What is LM741 op-amp?

The LM741 series are general-purpose operational amplifiers which feature improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439, and 748 in most applications.

Is LM741 a comparator?

The LM741 is an operational amplifier IC that can function as a comparator. It is an op amp chip that has 8 pins in total.

What is the difference between LM741 and UA741?

The LM741 series are general-purpose operational amplifiers. The UA741 is a high-performance monolithic operational amplifier constructed on a single silicon chip. It is intended for a wide range of analog applications.

Why do we use slew rate?

Slew rate helps us identify the maximum input frequency and amplitude applicable to the amplifier such that the output is not significantly distorted. Thus it becomes imperative to check the datasheet for the device's slew rate before using it for high-frequency applications.

What are the different kinds of packages of IC 741?

The different packages available for IC 741 are 8-pin metal, 10-pin flat pack, 8 or 14 pin DIP. The 741 IC was designed by Dave Fullagar of Fairchild semiconductor in 1968.

What is offset null IC 741?

The op amp offset null circuitry adds a balance capability to the input circuitry as shown in the example of the 741 op amp input stage. The op amp offset null connections enable the input circuit balance to be obtained by applying external circuitry.
