Explanation: When a signal is applied to the input of only one op-amp, some signal will appear at the output of other op-amp due to the physical closeness of op-amps in dual and quad packages, this causes amplifier to amplifier coupling. 7. A parameter which is applicable only to dual and quad op-amp is
A. Channel separation
B. Gain bandwidth product
C. Long term input offset voltage stability
D. Equivalent input noise voltage and current
Answer:A
Explanation: When a signal is applied to the input of only one op-amp, some signal will appear at the output of other op-amp due to the physical closeness of op-amps in dual and quad packages, this causes amplifier to amplifier coupling. 7. A parameter which is applicable only to dual and quad op-amp is
A. Channel separation B. Gain bandwidth product C. Long term input offset voltage stability D. Equivalent input noise voltage and current
Explanation: Channel separation is specified in the dual and quad op-amp data sheet because it is a measure of the amount of electrical coupling between op-amps that are integrated on the same chip. 8. Select the parameter that is not included in the evaluation for ac applications.
