• AD5175 AD5231 life cycle

    Hello

    How many times wiper position of AD5175 and AD5231 can be changed?

    Does "50-times programmable (50-TP) wiper memory" of AD5175 means that if MCU changes 50 times resistance this IC breaks down?

    Thank you

    AD5231 datasheet page19中的图43中只有1023个Rs,则应该有RAB= 1023*Rs,可是图中注释为RAB=1024*Rs,是否自相矛盾?


    page20中的公式(1)RWB=D/1024*RAB+RW 是否应该改为RWB=D/1023*RAB+RW


    另外,图43中的SWB和SWA是否也有电阻,电阻是多少?

    Unfortunately, the only digital potentiometer with three terminals that have 1024 steps are SPI parts. These are the AD5292 and the AD5231.

    Hi Marcus,

    On table 9 of the AD5231 data sheet, there is a footnote (3) that says "O1 and O2 data stored in EEMEM locations is transferred to the corresponding digital register at power-on, or when Instruction 1 and Instruction 8 are executed.".…

    Hi pavanbabut,

    Im happy that the problem is resolved .

    answering your question, 8.65k could be possible, remember that the AD5231 has a tolerance up to -40% to 20%.

    In case you are interested Analog is improving these values, which are quite common…

    I received this question from a customer:

    We are having problems with the AD5293 digital pot.  We are having problems with it on a prototype board.  It consistently locks up the SPI bus (specifically the MISO pin).

    Initially, we took no precautions in…
