I need switch signals between DAC (0-5V) and DDS generator (0-2.5V)
Please see the scatch
I have no idea how to connect this simple circuit in a wrong way. But as a result it seems that 2 channel work in parallel.
I mean signal from 's1' add to 's2' and in 'd' we have sum of those signals.
Can you share the schematic of your application circuit?
