Simulate µA702

Hello

For self-educational (and nostalgical) reasons, i've assembled a simulation of the µA702, which, as i understand, was the first monolithic OpAmp IC in production.

I've used LtSpice and its discrete transistor models. Most certainly,
these do not behave like their on-die counterparts in the IC.

I wonder if you could provide models or parameters to make the
simulation more accurate?

I already asked the Fairchild(now onsemi)-Support. The answer was "The µA702FM looks like old Motorola part and we do not support it". Which is a bit surprising, as the datasheet is labeled clearly as a Fairchild product.

So now i'm here as Motorola/Freescale has been aquired by NXP.

Any feedback would be appreciated.

Thanks

Holger

Hello,

It seems that there was confusion, it definitely does not belong to NXP and therefore we have no models for this device.
