Project 8-2 The Operational Amplifier

This is the support page for the Operational Amplifier project in Complete Electronics Self-Teaching Guide with Projects.

Parts List:

  • One 0.1 F capacitor.
  • Resistors.
    • Two 10 kΩ, 0.25-watt resistors.
    • One 51 kΩ, 0.25-watt resistor.
    • One 100 kΩ, 0.25-watt resistor.
    • One 150 kΩ, 0.25-watt resistor.
    • One 220 kΩ, 0.25-watt resistor.
    • One 270 kΩ, 0.25-watt resistor.
    • One 330 kΩ, 0.25-watt resistor.
    • One 380 kΩ, 0.25-watt resistor.
  • Two 6-volt battery packs (4 AA batteries each).
  • One function generator.
