Hey Team,

My customer is asking if it's okay to short pin NR and VREF together? Will there be any adverse effects?

Hello,

Shorting the NR pin and VREF pin could alter the performance of the device negatively. Please recommend that the customer do not short these pins on REF35. If they need to short pins 5 and 6, they could consider a device like REF4132 ( https://www.ti.com/product/REF4132 ) or REF3425 ( https://www.ti.com/product/REF3425 ) which would allow for a layout as you described, and could work as a drop in replacement.

Thanks,

Jackson
