Qs on Analog Switch, ADG412

[user1504]

I am trying to simulate a Charge/Discharge circuit in Multisim, Circuit1.ms10. A error occured during simulation. I thought the error comes from the Quad Switch, ADG412 after testing session by session. It is impossible to plug a voltage supply on the switch. See part1.ms10, when connecting a DC-Power source to the switch, a error occur. But when changing it with a DC-current, it works.  Why?

Hi there,

I think you have your power supplies in reversed. Your positive supply (VDD) is labeled -12V and your negative supply (VSS) +12V. Really it should be the opposite. Try setting your positive supply (VDD) to +12V and your negative supply (VSS) to -12V.

That should help.
