What is the minimum number of terminals required in an IC package containing four operational amplifiers (quad op amps)?
The minimum no of pins required by dualopamp is 8. Each opamp has 2 input terminals(4 pins) and one output terminal(2 pins). Another 2 pins are required for power.
Similarly, The minimum no of pins required by dualopamp is 14: 4*2 + 4*1 + 2 = 14.
Which of the following is not a property of an ideal operational amplifier?
An ideal operational amplifier does not has a zero input impedance.
In an ideal op amp the openloop gain is 10^{3}. The op amp is used in a feedback circuit, and the voltages appearing at two of its three signal terminals are measured as v_{2} = 0V and v_{3} = 2V where it is assumed that v_{1} and v_{2} are input terminals and v_{3} is the output terminal. The value of the differential (v_{d}) and commonmode (v_{cm})signal is
V_{c} = 0.5(V_{1} + V_{2}) and
V_{d = V2 – V1.}
Consider the figure given below. Known that vo = 4V and vi = 2V, determine the gain for the op amp assuming that it is ideal except for the fact that it has finite gain
The Voltage at the positive input has to be 3.000v, v_{i} = 3.020v
A = v_{o} / v_{i} – v_{r} = 2 / 3.020 (3) = 100.
Which of the following is not a terminal for the operational amplifier?
There are three terminals for the operational amplifier.
Operational amplifiers are
It is another way to refer to op amps based on its terminal characteristics.
Express the input voltages v_{1} and v_{2} in terms of differential input (v_{d}) and commonmode input(v_{c}). Given v_{2} > v_{2}.
This is the correct mathematical representation.
What is the minimum number of pins for a dual operational amplifier IC package?
The minimum no of pins required by dualopamp is 8. Each opamp has 2 input terminals(4 pins) and one output terminal(2 pins). Another 2 pins are required for power.
For an ideal operational amplifier (except for the fact that it has finite gain) one set of the value for the input voltages (v_{2} is the positive terminal v_{1} is the negative terminal) and output voltage (v_{0}) as determined experimentally is v_{1}= 2.01V, v_{2}=2.00V and v_{0}= 0.99V. Experiment was carried with different values of input and output voltages. Which of the following is not possible considering experimental error?
Only option d does not satisfies the mathematical relation between the given quantities.
