[sdiy] the obscure output of a 2164

[Busby Bergson]

hi list-

my eyes glaze over a bit with datasheets - and experts have better advice,
anyway :
i'm seeing a lot of designs with the output of a 2164 directly patched to
an op-amp....an inverting amplifier arrangement, with a feedback loop,
usually somewhere between 30k and 300k..... i have no idea how to calculate
the gain of this, though, because i'm unclear on exactly what's coming out
of the 2164.. any pointers?
