I have followed the Sallen-Key-Bandpass Filter example. It demonstrates the use of a Dual OpAmps chip. Details are provided here.
What I would like to do: develop a board (with simulation and PCB design) that contains several MCP6002 chips (again, dual op amp).
On a side note : I was able to adapt the Sallen-Key-Bandpass Filter example for the MCP6001 model, with a few adjustments detailed here.
The problem that I face is when I want a second Dual OpAmp chip on the scheme. Simulation gives me:
Too few parameters for subcircuit type “tl072c” (instance: xxu2)
It may have to do with the syntax of the TL072c: “XU1A …”. I tried to write a new model that just substitutes “XU1” for “XU2” (U2 being the reference of the second chip), with no success.
Any idea ?
