Module 4 Chips and Op Amps

The "-" sign on an operational amplifier is called the:

• Inverting Input

• Non-Inverting Input

• Output

An "Ideal Op-Amp" exhibits several characteristics. Pick the characteristic which DOES NOT apply:

• Infinite gain

• high output impedance

• infinite bandwidth

• infinite input impedance

There are 3 stages of an op amp. Pick the stage that does not apply:

• Differential Amp Input Stage

• Current Driver Stage

• Voltage Amp Gain Stage

• Push-Pull Amplifier Output Stage

What would be the output if the input signals are identical?

• max

• min

• 0 Volts

Negative feedback ___________ the input signal

• multiplies

• re-enforces

• opposes

This type of feedback is called:

• closed loop

• open loop

• Inverting Amplifier

• Non-Inverting Amplifier

• Comparator

• Zero Level Detector

The type of op amp that would turn a saw tooth input to a square wave output

• summing amp

• integrator op amp

• differentiating op amp

• integrator

• differentiator

• inverting amp

A zero level detector op amp can be modified to a different value (other than zero) by using what component?

• capacitor

• transformer

• zener diode
