• AD7814 Temp sensor SDOUT VOH

    Hi,

    We are using AD7814 temperature sensor interfaced with FPGA via SPI.

    VDD = 3.3V

    FPGA BANK Voltage 3.3V

    As per datasheet VOH and VOL for digital output as given below,

    But we are getting 1.2V in SDOUT which is neither high nor low as per datasheet…

    Hi,

    According to the silicon anomaly, dummy read is required.

    After dummy read, How many seconds is waiting till the next read?

    How many modes does AD7814 have?

    -normal mode

    -shutdown mode

    -automatic conversion mode

    Is "normal mode" the same as…

  • Current consumption of AD7814

    Hi

    In normal mode, Seral bus will be active.

    Q. Does the AD7814 have another mode with inactive serial bus?

    I want to know how much current will be consumed in normal mode with inactive Serial bus.

    Thanks.

  • RE: Question about EVM of AD7814

    Hi JakeKim,

    Would you like to have an evaluation board for testing how the part works? If so, I'm afraid we don't have any evaluation board on this part, but I would suggest to have a look to the following ones, that have the same interface and package…

  • Is the serial interface active in normal mode of AD7814?

    Hi

    When you measured the current consumption in the normal mode.

    In this case, Is the serial bus active or inactive?

    Hope to get prompt answer.

    thanks

    Hi, the nearest parts to AD7314 are AD7814 and ADT7301. Eval kits are available for ADT7301.

  • Is ADP2291 working as expected in the datasheet or its examples are fail?

    Hello Everyone,

    Im working on a battery charger circuit. I set completely the figure-22 and the figure-23 in the datasheet. So more than hundred try and later than weeks. The circuits are not working as expected. This part is important "The circuits are…
