What is the ideal value of bandwidth for 741 IC op amp?
1MHz
For 741: 1MHz (approx.) Also called as: Closed loop bandwidth or.
How many transistors are in a 741 op amp?
20 transistors
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 are AC and DC parameters of op-amp?
Opamps are used to amplify both AC and DC signals. However, opamps have limited response speed, and therefore cannot handle all types of signals. In the above diagram [Slew Measurement Circuit and Waveforms] of a voltage follower circuit, the input and output voltage ranges are restricted by the DC input voltage.
What are the ideal characteristics of op-amp What are its parameters and how it measure these?
An ideal op amp is usually considered to have the following characteristics:
- Infinite open-loop gain G = vout / v.
- Infinite input impedance Rin, and so zero input current.
- Zero input offset voltage.
- Infinite output voltage range.
- Infinite bandwidth with zero phase shift and infinite slew rate.
Which is incorrect parameters of an ideal op-amp?
Explanation : An ideal Op-Amp has an infinite CMRR, Slew Rate & Bandwidth. But, the output voltage is absolutely zero when the input voltage is zero. All the mentioned parameters tend to infinity except output voltage & resistance so that it becomes feasible for an output to drive infinite number of other devices.
What is the saturation voltage of 741 in terms of VCC?
For a 741 op-amp powered with VCC= +10V and VEE= -10V, Vo will saturate (reach the maximum output voltage range) at about ±10 V. With an A=200,000V/V saturation occurs with an input differential voltage of 10/200,000 = 50µV, a very small voltage.
