Default Re: Analog Devices 45K (AD45K?)

Your eyes must be better than mine- I'd skimmed through that document as just about the only useful looking search result.

Pity I can't return the card with C12 circled!

Adding op amp to the search turned up an Analog Devices OP amp history section in their OP Amp Applications book which identified the 45 (presumably a forerunner of the 45K) as a FET input fast settling opamp.

Haven't found a spec yet though.....
