Which of the followings is not a specification of an ideal op-amp?

a) unlimited bandwidth.
b) zero supply current.
c) zero input current.
d) zero output impedance.

b) zero supply current.

The characteristic of a voltage follower include:


a) high voltage gain
b) low input impedance and high output impedance
c) high input impedance and low output impedance
d) medium voltage with wide bandwidth

c) high input impedance and low output impedance.

In a AD624AD Circuit, what is the amplitude of the output voltage?

VEE = -9V
VCC = 9V
V1 = 10 MVpk, 1 kHz

Without more information about the specific configuration of the AD624AD circuit, we cannot determine the amplitude of the output voltage. The AD624AD is a versatile instrumentation amplifier that can be configured in a number of ways, using external resistors and other components to set its gain and other characteristics. The output voltage will depend on the specific circuit configuration and the values of the external components used.

The maximum voltage gain of an op-amp is 100,000. The voltage gain at the cut-off frequency is:

a) none are correct
b) 97 dB
c) 50 dB
d) 100 dB

a) none are correct.

The question cannot be answered with the given information. The cut-off frequency depends on the specific circuit configuration and the components used, not just on the op-amp itself. Additionally, the voltage gain at cut-off frequency will depend on the particular circuit's design and its frequency response characteristics.
