how is the sensitivity and potential of the trim pin of adr444

there is no specification in the datasheet.

  • Hi Wrmin,

    ADR444 is based on ADI XFET technology which includes a trim terminal that allows output voltage adjustment over a ±0.5% range. For more information regarding output voltage adjustment please see applications information located on page 16 of the ADR444 data sheet.

    While trimming please make sure to add series resistance R1 followed by potentiometer or fixed resistors. Please see figure below.

     

    What trim output voltage you are trying to achieve and initial accuracy?

    Regards,
