Is there a suitable substitute for the CA3140 op amp in Multisim 11.0?

Is there a suitable substitute for the CA3140 op amp in Multisim 11.0?

‎03-06-2011 08:28 PM

I'm looking for a comparable substitute for a CA3140 op amp for a project. From what I've read, it's a mosfet type amp with an extremely high input impedance of about 1 Tera-ohm. The only substitute I'm finding is the NTE 7144, however this doesn't appear to be in multisim.

Hi,

 

Multisim 12 has CA3140 opamp now! If you have SSP you are eligible to upgrade for free!
