digital poti question

[cheerio]

Hi,
i need a digital poti that survives ~24V on its resistor terminals. All digital potis i found do only survive the operating voltage of the chip on their resistor terminals. Are there any digital potis for my application or do i have to make a resistor array myself?
The voltage applied to the resistor terminals is between 0V and 24V. I found some potis that work with ~30V supply voltage but i would like to use ~5V supply voltage and still use 0V-24V on the resistor terminals? any chance?

thank you in advance

I've never met such a digital pot! Maybe you can interface it with a transistor?

i Think that will suit your requierments.

was looking at this already. the problem here is that the input voltage can drop to <1V and the poti won't work with that afaik. Thats why i would love a fixed supply voltage. i think i will make a resistor array :/
