Electronics C8

A differential amplifier

• is a part of an Op-pam

• has two outputs

• has one input and one output

• Both A and B

With zero volts on both inputs, an OP-amp ideally should have an output

• equal to the negative supply voltage

• equal to zero

• equal to positive supply voltage

• equal to CMRR

For an Op-amp with negative feedback, the output is

• increased

• equal to the input

• fed back to the inverting input

• fed back to the noninverting input

The Op-pam can amplify

• DC signals only

• AC signal only

• both AC and DC signals

• Neither AC nor DC signals

An ideal operational amplifier has

• Infinite bandwidth

• Infinite output impedance

• Zero input impedance

• All of the above
