  • What ohm EVAL-AD5270


    My customer is considering EVAL-AD5270.
    If my customer orders EVAL-AD5270, what type of AD5720 is implemented?
    ORDERING GUIDE lists resistance values of 20k ohms, 50k ohms and 100k ohms.

    Best regards
  • RE: AD5270 as NTC controlled by Arduino

    Hi Wolle,

    Can you tell me about the application you are designing?

    The AD5270 uses SPI communication, while the AD5272 uses I2C communication:


    Arduino          AD5270

    PB5: SCLK   Connects to SCLK on the AD5270 (Pin 9)

    PB4: MISO   Connects to SDO (Pin…

  • AD5270电阻为负值?



    Hi Takahiro,

    AD5270/1 has two modes of operation:

    1. R-Performance mode: where the resistor tolerance can be upto 1% based on table 2 and 3 in the Datasheet.

    2. Normal Mode: where the typical resistor tolerance is 15%.

    By default the R-performance is…

    Hi Rainier,

    Thank you for your reply. i using 3series  AD5270 for test circuit.

    I modified it the way you suggested. AD5270 still doesn't change resistor value .  Please refer followings;
