NOT good for audio rate circuits where the leakage and parasitic capacitance will cause trouble. The diodes across
the inputs rely on the opamp being fast enough to make the negative input follow the positive input... not always true with fast moving cignals.
Beginning to wonder if this whole input protection idea isn't more trouble than it's worth at best and at worst - merely placebo?
I know there's not going to be a one size fits all solution... but I thought I'd gotten 'near enough' with this current schematic.
