Op-Amps (2)
Non-Inverting Amplifier
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?
Annotation
Non-Inverting Amplifier
VCC=9VVEE=-9 V
VIN=0.5 VVOUT=3 V
Set Up the Simulator for DC Sweep

Gain of 6!
Difference Amplifier
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?
