Re: A/D Precision on a budget

In the current Farnell catalogue they list a bunch of precision thin-
film resistive dividers with ratio tolerances of 0.05% and better, and
a couple of Vishay thin film eight resistors arrays - 1k, 10k and 100k
resistors with an absolute tolerance of 0.1% and a ratio tolerance of
+/-0.05%.

They alos carry a couple of ranges of 0,1% 15ppm resistors on the E96
grid and a much smaller range of 0.01% 0.6ppm/C resistors.

Digikey has some nice Vishay resistors, too:

+/-2ppm/°C and +/-0.01% tolerance, but it costs $11.52.
