What does 741 IC mean?
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 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 offset 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.
What is monolithic op-amp?
Monolithic Operational Amplifier Works from ±4.75V to ±70V and Features Rail-to-Rail Output Swing and Low Input Bias Current. by Michael Anderson Download PDF. Monolithic operational amplifiers have been around since the 1960s, but this ubiquitous device still sees steady improvements in performance.
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.
Which IC is used in op amp?
IC 741
An op amp is a complex electronic device, which consists of resistors, capacitors, transistors and diodes. It is commercially available in integrated circuit form. Most commonly available and used op amp IC is IC 741. The IC 741 is a small chip.
What is NC in op amp?
Many times, chips such as op amps, have a NC terminal, which stands for Not Connected terminal. This terminal should stay unconnected, meaning it should not be connected to your circuit at all.
Is op-amp a transistor?
The standard 741 Op-amp circuit contains 20 transistors and 11 resistors. It starts with a differential input stage with a current mirror load. This is followed by an npn voltage amplification stage with an active output. A pnp emitter follower drives a push-pull emitter follower output stage.
What is CMRR of op amp?
The op amp common-mode rejection ratio (CMRR) is the ratio of the common-mode gain to differential-mode gain. For example, if a differential input change of Y volts produces a change of 1 V at the output, and a common-mode change of X volts produces a similar change of 1 V, then the CMRR is X/Y.
What is gain RF?
RF amplifier gain is defined as the difference in power between the amplifier output signal and the input signal. It is assumed that both input and output impedances of the amplifier are the same as the characteristic impedance of the system.
Why is it called op amp?
Op-Amp (operational amplifier) Originally, op-amps were so named because they were used to model the basic mathematical operations of addition, subtraction, integration, differentiation, etc. in electronic analog computers.
