Measuring the Output of the Amplifier

Before connecting the servo controller, you should test the other portions of our board to make sure they are working.

  1. Turn on your circuit.
  2. Set the multimeter to read DC voltage.
  3. Test the amplifier you designed by applying a small DC voltage () at the non-inverting input and determine if the output voltage is what you would expect it to be.
  4. Disconnect and connect the non-inverting input to .
  5. Connect the multimeter across the output of the amplifier.
  6. Vary the potentiometer from one extreme to the other, to find the range of values you can obtain at the output of the amplifier. Record this range.
  7. Is the range great enough to drive the servo controller? If not, you should redesign the amplifier to give greater amplification.
