Text ## Lecture (L4-1) Op-Amp Characteristics

An operational amplifier (op amp) is one of the most widely-used components in electrical engineering.  Op amps can be built into circuits to amplify/de-amplify, compare, add, subtract, multiply (that's amplify), and divide (that's deamplify) a voltage. 

Questions of the Day (Learning Objectives)

  1. What is an Op-Amp?
  2. What is the linear range of the op-amp?
  3. What is the difference between the op-amp gain (A) and circuit gain (G)?
  4. How is an op-amp used as a switch?  (what values can it switch to?)
  5. An op-amp is characterized by three important input/output attributes. What are they?
  6. What is the equivalent circuit model for an op-amp (working in the linear range)?
  7. What is an ideal op amp, and what approximations can we use?
