AD5175 AD5231 life cycle

50-TP is where you can write 50 times into EEPROM to change the wiper position on powerup. After that, the EEPROM will not accept any more writes. The device will not break down on writing more than 50 times into EEPROM.

However, you can write directly into RDAC register to change the wiper position with no upper limits.

For AD5231, write cycle is at least 100000.

100000  for EEMEM or RDAC?

For EEMEM.

So RDAC can be used unlimited times.  Thank you very much!

That is correct.
