PC/CP300 Electronics Laboratory II

Operational Amplifiers Building Block

Create these two circuits on a two-bus breadboard and label the inputs and outputs. Be sure to colour code power and ground signals approriately. You will keep these circuits for future use.

Use a LM324 op amp and build both blocks with different amplifiers on the same chip.

  1. Buld a non-inverting amplifier with a gain of 3.
  2. Buld a differential amplifier with a gain of 1.

Demonstrate your working blocks at the next lab period.
