REF102: REF102 stacked : what is the maximum error?

F_F_S

Prodigy 140 points

Part Number: REF102

Hi,

on datasheet of REF102 (figure 11) is write that is possible to put more REF102 on stacked to obtain multiple voltage.

If I use 2 of REF102, what is the maxium error on 20V ?

Thanks?

Hi Floriano,

Yes you can stack voltage references. Section 9.3 of this document might help you out www.ti.com/.../slyc147.pdf
The DC errors ratio should be the same because when you stack 2 VREFs the errors add up but also the output voltage adds so the ratio stays the same.
