Error: Input Power pin not driven by output power pins

[lmp]

Hi there,
It’s important for you to know that I’m new with this.
I’m doing this circuit with opamps and it’s always giving this error: Input Power pin not driven by any Output Power pins. CAn anyone help me, please?
This is my circuit:

Hi @lmp

Pins for symbols, like everything else in Kicad, have “Properties”. To view pin properties, you need to open a symbol in the Symbol Editor. Below is an example. I have opened the list of “Electrical type” for pin 8 of an op-amp.

Your AD8066 has pins 5 & 4 selected as “Power Input” pins for their “Electrical type”.

The ERC is not very smart. For the ERC to be happy, any pin selected as a Power input MUST be connected DIRECTLY to a power output from somewhere… anywhere.

To make ERC happy, you have four choices:

• You can ignore the warning. It is only a warning.
• You can modify the pin properties to eg. passive, so ERC will not be upset.
• You can place a power flag on the input on the net into the offending pin thereby telling ERC there is a power output connected to this power input.
• You can place a power output directly attached to the power input.

The two easiest are either ignore the warning or place a power flag.
You will find the “Power Flag” symbol in the Symbols “Power” library, towards the bottom of the list.

I’ll also recommend reading the documentation @Piotr suggests, as well as the rest listed here.

Thank you very much
