4069 as an amplifier spice model?

Hi,

Anyone know of a spice model for a 4069 buffer being used as an amplifier? If there is one in pspice I can't find it.

Or come to that, info on what the params for a 4069 used as an amplifier are.

TIA

Hello Malcolm, there has been a similar question in sci.electronics.design in November(11/18/2004). The original postings are attached.

LAMBDA=1.87M

You copy the text into notepad and then save the file with a .asc extension. LTspice will then open it up as a schematic.

Hi Helmut,

Thanks. I'd missed that thread.

Hi Jim,

Thanks for the offer. I'll bear it in mind if I ever need the HC04 but for now the 4069 would suit better as the supply voltage range is more.
