What is the maximum output current that the 741 can supply?
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.
What is output of follwing circuit of op amp 741?
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.
Which is the output of IC 741?
The 741 IC draws in power for its operation from these pins. The voltage between these two pins can be anywhere between 5V and 18V. Pin6 (Output): This is the output pin of IC 741.
What is the gain of a 741 op amp?
about 2,00,000
741 Op-Amp Characteristics 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 maximum input voltage for 741 opamp?
(1) Unless otherwise specified, these specifications apply for VS = ±15 V, −55°C ≤ TA ≤ +125°C (LM741/LM741A). For the LM741C/LM741E, these specifications are limited to 0°C ≤ TA ≤ +70°C.
How does 741 op amp work?
The most common Op-Amp is the 741 and it is used in many circuits. The OP AMP is a ‘Linear Amplifier’ with an amazing variety of uses. Its main purpose is to amplify (increase) a weak signal – a little like a Darlington Pair. The OP-AMP has two inputs, INVERTING ( – ) and NON-INVERTING (+), and one output at pin 6.
What is the typical input bias current of a 741 operational amplifier?
There is a tiny input bias current for an op-amp which is about 80 nA for 741 type op-amps. For high speed one may choose an op-amp with higher bias current at the cost of seeing some voltage drop across the resistors of the feedback network, bias network or source impedance.
What is the output for an op-amp with negative feedback?
feedback to the non-inverting input. Answer. 113.7k+ views. Hint: Negative feedback refers to providing feedback to the inverting input terminal.
What is the maximum input offset voltage in 741 op-amp?
Input Offset Current 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.
How will be the output of the operational amplifier?
An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.
What is the output for an op amp with negative feedback?
What is the ideal value of output impedance for 741 IC opamp?
In practice, the voltage gain for a typical 741-style op amp is of order 200,000, and the current gain, the ratio of input impedance (~2−6 MΩ) to output impedance (~50 Ω) provides yet more (power) gain.
What are the uses for a 741 op amp?
The 741 op-amp is a general purpose amplifier. It can be used to regulate power supplies, made into a simple signal generator, used as an oscillator, used as a radio or TV receiver, used as a timer, or used as a filter. It is also used extensively for instrumentation (metering current or voltage).
Why does op amp called with 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.
What are the applications of opamp 741?
