It's no coincidence that virtually all 8.5 digit DMMs use the LTZ1000. It's in a class of it's own. REF102 is not in the same class, even if you average a handful.
But there are a couple of nice things about the REF102, though for more moderate requirements - You get a reference at 10V, +/-0.0025V, trimmable (not a 5% 7V of the LTZ1000) - Moderate power / current - Low sensitive to supply voltage - Very simple to implement There was a metal can version but it's obsolete. But be aware that the TI site still shows the metal can spec 5ppm/1000h while the available packages are actually 20ppm/1000h! _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
