Frequently Asked Question

Will the data in the EEMEM need to be refreshed after 15 yrs when it is operated at 55°C?

Yes. The EEPROM cells will lose charge over the 15 years when operating at 55°C. For other operating temperatures please see the "Retention vs. TJ Junction Temperature" plot in the AD5232 datasheet. Such data applies to all nonvolatile memory digital potentiometers.
