[AD5165] wiper position after power-up

Hello,

I cannot find AD5165 wiper position after power-up.

According to AN1291, there are two type of DigiPot that have POR or not. And default state of wiper position is depend on POR integration or not in DigiPot.

If AD5165 have POR, default wiper position is mid scale, I suppose.

But I cannot find such a information in Datasheet.

So AD5165 default wiper position is not stable after power-on, isn't it?

Thank you for your help as always.

Best regards,

Sofy
