Hello fellow electronic enthusiasts!
Is there such a thing as a non-volatile digital potentiometer that will operate as usual when the power is removed from it? The application is for a deep sleep circuit with a calibration potentiometer that essentially governs when the system comes back out of sleep. The value of the pot won't be changed during deep sleep, but it does need to operate. Worst case, I'll use a low quiescent digipot that will have constant power, best case there's a device out there that will still behave properly when the power is removed.
If there isn't, are there any low quiescent, low voltage (direct lipo power, ~2.5V to ~3.7V), SPI controlled digipots out there that anyone could recommend?
Cheers for your help guys,
Dan
