• RE: ADAQ7980 usage as current sense

    Hi Naresh,

    ADAQ7980 can be use in a wide variety of application. e.g current to voltage application.

    ADAQ7980  provides the flexibility of a configurable ADC driver feedback loop to allow gain and/or common-mode adjustments.

    Here's some reference circuit…

  • ADAQ7980

    We have experienced a string of failures with this component after replacing some of the surrounding discrete components leading to the amplifier.  All typical ESD precautions aside, is anyone aware of particular sensitivities when performing hand (not…

  • ADAQ7980

    The datasheet suggests a power sequence for the single-supply implementation.  Are there any timing requirements between each event?

  • ADAQ7980 SDO Output

    Our current design is using the ADAQ7980.  We are reading the correct data over the SPI bus.  However, when looking at the signals using an oscilloscope we noticed a strange RC type response on the SDO line during the assertion of the CNV signal.  Can anyone…

  • About ADAQ7980

    Hi,

    I would like to use ADAQ7980.

    I have two questions.

    #1   What is the power supply for Reference Buffer?

    #2   It is written that Gain is stable with unity gain  on page 28 of datasheet.

    　   And, Open-Loop Gain is written as 111 dB.

    　   How much can a…

  • About ADAQ7980 power consumption

    Hi,

    I would like to use ADAQ7980.

    So, I have three question.

    #1  What is the total current consumption when Sampling rate is reduced to its limit?

    　  (ADC Driver, Reference Buffer, LDO enable)

    #2  What is the total current consumption when Sampling…

  • ADAQ7980/88中单电源5V供电时，模拟输入电压的问题

    关于ADAQ7980/88中单电源5V供电时，模拟输入电压的问题

    如上图中所示的Min的0.15V,是否意味着当仅+5V供电时，模拟输入电压范围为0.15V~VREF？

    期待答复，谢谢。
