Decompensated, gain >=7, but pretty cool.

That page sucked..(wanted info) here's the product page.
It's cheaper than I thought it was going to be; I guessed 15 bucks in singles.

For a gain of 10 it is dead above 20 MHz? Use a tranny ;-)
Yep; cf. Win's x-chapters thread. Current consumption is a bit on the high end though, as to be expected given the specs.
They mention it using SiGe in the datasheet; I wonder what the technology distribution is across fast op-amps.
Have you tried some samples yet?
? David
Not yet. They're going into a fast, low noise VCA for that cathodoluminescence product. It needs a fair amount of gain at up to 40 MHz, so an OPA818 with a series RC from the SJ to ground is the ticket--that'll stabilize it at unity gain, and the corner frequency can be up around 350 MHz where I don't care about the noise very much.
