I want to use a dual package OpAmp. Looking at the available symbols, the dual OpAmps are split up into two individual symbols, which is typical. What I have not seen before is that both symbols have power and ground pins. The pin numbers are the same, 8 and 4 on both symbols. The other pin numbers change to reflect the two different OpAmps in the same package.
How should i treat the two sets of power and ground pins? Hook them both up or leave one set disconnected?
Yeah, that clutters the schematic a little but it’s a very minor annoyance. (Trust me.)
One possible alternative is to re-draft the component as a THREE section component: two sections for the opamps themselves (WITHOUT power pins), and one section just for the power connections. Then you can tuck the power section into a corner of your drawing, where you show the power connections to ALL of the IC’s and modules in your design, along with decoupling capacitors, common-mode chokes, fuses, and other stuff associated with power distribution. No, I don’t draft my schematics that way but it IS a reasonable approach.
Today this approach is a bit worthless because making that three unit component you have to disable automatic unit interchangeable and manualny controll of unit distribution before or after auto annotation. If the devs don’t screw it in incomming new schematic and library file format such approach will be very good, today it make unnecessary manual work.
