28 Chapter 2 – Schematic Capture Editor

Using our working design, add 2 more 0V symbols. From the Add Component browser, this time add one +15V symbol and place near C3. Now add one -15V symbol, place it near C4.

Drag a connection off the end of the symbol terminal and connect as shown below. Your design will look something like this:

Generally speaking you would now need to add some connector pins to connect the circuit to the outside world.

Adding Connectors

For this example, we will use a connector component from the library.

 To add Connector pins

Using the Add Component browser from the Interaction bar <F9>. Choose a new library, select the Conn_std component library.

Select the 5WP connector component from the list. The PCB Symbol and Schematic Symbol previews will be displayed.

Drag it into the design and place it near the resistor R1 as shown below:

Connect in the connector to the design using Add Connection or by dragging off a pin. You will also need to add another +15 component for completeness. Your design should look like this below:
