<div>These diode are indeed clamping the output, but a zener will not
conduct until it reaches it's rated voltage. 3080s are also pickier in
usage (and pricier) than opamps usually.</div>
<div>From what I can see, this above will rectify everything. With a
zener, you could pass an undisturbed sinewave, with only the peaks
being limited past the zener voltage.</div>
<div>Someone correct me if I'm wrong though. I'm no engineer.</div>
<div>More of a "if it works and doesn't draw too much current,
it's probably ok" school ;-)</div>
<div><br></div>
<div>Btw, I recently picked up a bunch of NOS TO-5 (metal can) CA3080H
OTA's.</div>
<div>If anyone needs some in this round style package, drop me a
private email. :)</div>
