Try these first

1. 1.

   What is an operational amplifier?

   Hint

   Think about its basic characteristics and functions.

2. 2.

   What does IC 741 signify?

   Hint

   Recall the common examples of Op-Amps.

3. 3.

   What type of inputs does an operational amplifier have?

   • Single-ended inputs
   • Differential inputs
   • Both

   Hint

   Focus on the definition of operational amplifiers.

4. 4.

   True or False: The IC 741 has a very low gain.

   • True
   • False

   Hint

   What do you remember about its amplification power?

5. 5.

   Design a simple circuit using IC 741 to create an inverting amplifier with a gain of -5. What resistor values would you choose?

   Hint

   Use the Av formula for inverting amplifiers.

6. 6.

   If you apply a 1V input to a non-inverting amplifier circuit built with IC 741 and Rf = 20kΩ, R1 = 5kΩ, what would be the output voltage?

   Hint

   Focus on the non-inverting amplifier gain formula.
