Summary

The supply pins on CL opamps are not polarity sensitive. You can set either supply pin to any voltage and the other to any other voltage and the model will correctly pick up which is the highest voltage supply limit and which is the lowest.


Description

The supply pins on CL opamps are not polarity sensitive. You can set either supply pin to any voltage and the other to any other voltage and the model will correctly pick up which is the highest voltage supply limit and which is the lowest.

So if you set one pin to -5V and the other to +5V then the model will run with a high output limit of +5V and a low limit of -5V, irrespective of which supply pin is connected to the +ve and the -ve supply voltage.

In general, if you set either pin to Va and the other to Vb where Va > Vb then the model will operate with a high limit of Va and a low limit of Vb.

This is true even if Va > Vb > 0 or 0 > Va > Vb.

Try editing the supply pin voltages.
