2.2.10 Rated Opamp
An ideal operational amplifier (Opamp) is an amplifier with infinite gain, infinite input
impedance and zero output impedance. With the application of negative feedback, Opamps
can be used to implement functions such as addition, subtraction, differentiation, integration,
averaging and amplification.
An opamp can have a single input and single output, a differential input and single output, or
a differential input and differential output.
Note Refer to the Component Reference Guide for a more detailed discussion of opamps.
To adjust the component’s tolerances:
1. Double-click on the placed component and click the Value tab.
2. Change the following values as desired:
Animation Delay Factor — increase this number to slow the speed of animation of the
symbol blowing. This is not a real-time value.
Maximum Supply Voltage (+/-) — the maximum voltage (+/) allowed. If this value is
exceeded during simulation, the opamp blows.
Maximum Input Voltage (+/-) — the maximum input voltage (+/) allowed. If this value
is exceeded during simulation, the opamp blows.
Maximum Differential Input Voltage — the maximum differential input voltage
allowed. If this value is exceeded during simulation, the opamp blows.
Maximum Sink/Source Output Current — If this value is exceeded during simulation,
the opamp blows.
3. Click OK.
