  2. Non-Inverting Amplifier

  3. Design Problem • Design a non-inverting op-amp with a gain of 6. • What is the approximate power supply if Vin must be kept between -1.5 V to 1.5 V?

  4. Annotation

  5. Non-Inverting Amplifier VCC=9V VEE=-9 V VIN=0.5 V VOUT=3 V

  6. Set Up the Simulator for DC Sweep

  7. Probe Plot Right Click on the line, copy to the clip board, Paste data to an editor Add a port before running the DC Sweep

  8. Data exported to a file Saturation Gain of 6!

  9. Difference Amplifier

  10. Design Problem • Design this amplifier for a gain of 8 • If VA is fixed at 1V and that power supply is +- 9V, what is the range of input voltage?
