• AD5274 user user guide with stm32 controller

    Hi,

    I am unable to find the initialization sequence for AD5274 with the stm32.

    Please provide me any user guide to use the AD5274 along with the stm32 controller (non os).

    Thank you.

  • AD5274 userspace driver

    We are using the ad5274 device to control an LCD contrast pin. I have successfully instantiated the ad5274 linux driver. The driver exposes a couple of files in /sys/bus/i2c/devices/000-02c. The files of note are rdac0, otp0en, and otp0. I can't find…

  • AD5274 shutdown mode

    Hi,

    I have a question about AD5274 in shutdown mode. From my understanding, the shutdown mode would provide infinity resistance between port A and port W. Am I correct?

    I'm using this chip to set the gain of an amplifier. I put the chip to shutdown…

  • Reg: Problem in Writing RDAC of AD5274 through I2C

    Hello All,

    I tried to change the RDAC Register value of AD5274BRMZ-20 (20K-Max) through I2C. But the resistance between the A & W pins is always constant to 9.25K(Mid Value).

    I have sent the following Values through I2C.

  • Parallel digital potentiometers

    Hello,

     

    In my application I will need four digital potentiometers (AD5272/AD5274), which I will connect parallel. Could you tell if that is possible? If it is possible, you can give instructions how I will manage this.

    Thank you,

  • AD5272 / AD5274 Power-up sequence

    Hello,

    Currently reading the datasheet of these components, I wish to ask you some more information about the power-up sequence.

    On page number 24 of the datasheet (revision C), I can read that the ideal power-up sequence is : 1.VSS, 2. VDD and then…

  • RE: AD5274 I2C controlable potentiometer programming issue

    Hi Peter,

    Could you clarify your problem? ie. the fuses wont get programmed, fuses blown correctly but the part does not power in the correct position...

    Additionally,

    do you read bit C3 after programming the part?

    do you read the last memory location…
