What is a 741 operational amplifier?
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.
What is maximum input voltage for 741 opamp?
+18 volts
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. The device will operate essentially the same over this range of voltages without change in timing period.
What is IC 741 function?
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.
How many pins are there in IC 741?
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.
What are the characteristics of IC 741?
741 Op-Amp Characteristics The Input impedance of the IC 741 op amp is above 100kilo-ohms. The o/p of the 741 IC op amp is below 100 ohms. The frequency range of amplifier signals for IC 741 op amp is from 0Hz- 1MHz. The voltage gain of the IC 741 is about 2,00,000.
What is the output impedance of a 741 op amp?
about 75 ohms
Op-amp Output Impedance For the 741 it is about 75 ohms but can be as high as several thousand ohms for some low power op-amps.
What is the unity gain bandwidth of the LM741 opamp?
Bandwidth (or gain bandwidth product, GBW): The gain as a function of frequency for smaller signals (i.e. the output isn’t limited by the slew rate). The LM741 has a GBW around 1MHz (but not listed in this datasheet). This means that with a 1MHz input the max gain is one (the gain drops off as frequency increases).

Why do we need op amps?
An op-amp is an IC that amplifies the difference in voltage between two inputs. Op-amps can be used for various applications, depending on the external components added. In the most basic circuit, op-amps are used as voltage amplifiers, which can be broadly divided into noninverting and inverting amplifiers.
What is comparator in op amp?
A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.
