I've just noticed that TI and Linear's specs for 'Long Term Stability'
(typical) are different. TI state 20ppm/1000Hr while Linear state
8ppm/SQRT(kHr). That's a big difference - is this likely to be a real
difference or just specmanship?
I note that Linear (in Note 4) also state that "Devices with maximum
guaranteed long-term stability of 20ppm/SQRT(kH) are available."
Presumably they would be a special order as there doesn't appear to be a
unique part no. Would they be likely to be much more expensive?
Isn't 8ppm/SQRT(kHr) better than 20ppm/SQRT(kH)? Why would the latter be
more expensive? Or is it the difference between "typical" and "guaranteed?"
