• AD5144

    This is a +5V part. Basically it has 4 rheostats - that is the mode I am using. I understand that the voltage across the terminals {A and B}  OR {AW and B} cannot exceed 5V. Please confirm this.

    Secondly, if the rheostat is used in a circuit the max…

  • RE: AD5144 doesn't load configuration on power-up

    Hi,

    Would you also be able to provide the teminal voltages of the AD5144? You may want to look at the power up sequence section of the AD5144 on page 32 of the RevA. data sheet.

    Regards,

    Hi Emman

    Thanks for your answer.

    This is the schematic I have used. AD5144 is a digital controlled potentiometers. The feedback resistor is consisted by AD5144 and one of the two registers (R10 and R9 for top path). ADG633 is used as switch to achieve…
