  • AD5141: Programmable LDO

    Q 

    I want to make a programmable LDO. What devices could I use?

     

    A 

    For this application, I'd recommend a digital potentiometer such as the AD5141
    plus one of our LDOs, in linear gain setting mode.

    You can select any of our LDOs, ie. ADP1708,…

  • AD5141: Operation below 2.3VDD

    Q 

    Can the part operate below 2.3V VDD?

     

    A 

    The part has not been characterizing below 2.3V due to EEPROM functionality
    restrictions. In other words, the EEPROM cannot be programmed below this supply
    voltage.

  • AD5141: Power Supply Sequence

    Q 

    What is the exact power-supply sequence? How long does it take?

     

    A 

    At power-up, the part resets all the internal registers, loads half scale in
    the RDAC and proceeds to read the EEPROM. Once the EEPROM is correctly read
    back, the part loads the…

  • How often can I write to the AD5141's  internal EEPROM?

    Q 

    How often can I write to the AD5141’s  internal EEPROM?

     

    A 

    It depends on the temperature, typical 1Mcycle @ 25C, minimum 100k cycles.

  • AD5121 / AD5141 Digital Potentiometer 

    I want to use 100K Digital Potentiometer
    
Looking at the data sheet for AD5121 / AD5141, 10k ohms / 100k ohms
    
AD5121: 10K ohm
    
AD5141: 100K ohm

Is it okay to think this way?

  • AD5141　Evaluation tool GUI

    Hi,

    My customer is considering using the AD5141 evaluation board.
    However, when the evaluation GUI is launched and the evaluation board is connected, the evaluation GUI shuts down.
    SDP-S is also connected.
    I checked the device manager, I can confirm it as…

  • AD5141 For Feedback loop of switching power supply

    Hi, 

    Can I use the AD5141 to replace both resistors in the feed back loop of a switching power supply? Should I use potentiometer mode or linear gain setting mode? 

    Thank you.

  • I²C Linux driver for AD5141 digital potentiometer

    Dear all,

    We are using a FPGA platform with an integrated ARM working under Linux.

    For our new Hardware we want to use the AD5141 with the I²C interface.

    Is there any Linux driver available for the AD5141 digital potentiometer?

    Or is there any guideline…
