Is this op-amp uV/C that high?

by Paul <energymover@[EMAIL PROTECTED] > Sep 10, 2008 at 08:21 AM

I'm try to figure what the offset voltage temp drift for the Ina116P
op-amp,

Ina116P datasheet:
http://focus.ti.com/lit/ds/symlink/ina116.pdf

At the bottom left side of page 5 is a chart. Looks like there's an
appreciable chance of getting an op-amp that near 20uV/C drift!  I
would like to build an electrometer that has extremely low input bias
current and low drift, but that kind of drift seems far to much. If
it's 20uV/C and a gain of 1000 then it's 20mV drift per C, correct?
I'm more used to op-amps like the AD8551, which has a typical drift of
0.005uV/C.


AD8551 datasheet:
http://www.analog.com/static/im****ted-files/Data_Sheets/AD8551_8552_8554.pdf


I appreciate any help or advice.
Paul
