• AD7789: External R-C

    I have a question about the CR circuit connected with the analog input of AD7789.

    Is the CR value of Table 14 in the AD7789 data sheet applied to the CR circuit type of the attached file?

    Regards,

    Mr.K

  • decoupling the AD7789

    Hi Experts-

    On page 18 of the AD7789 data sheet it says that a tantaulm capacitor should be used for bulk decoupling. Can we use a 10uF ceramic cap instead? it has lower ESR. Thanks,

  • AD7789 24bit ADC data register read issue (Arduino)

    Hello,

    I'm trying to use the AD7789 24 bit ADC with an Arduino, and I'm having an issue that every so often the AD7789 returns 0xFFFFFF when it shouldn't. This is for my EE senior design project at georgia tech, we're making a device that measures the…

  • AD7789 sensor 2.5V - all or nothing issue, 00..00 or 11..11

    Hello

    I have a sensor that provides its value between 0.5V to 2.5V.
    I am using an AD7789 with 2.5V reference voltage (ADR391) to REF +, ref- grounded. (AGND = DGND = global GND)
    AIN- to ground
    AIN + directly to sensor signal

    When reading the result of…

  • RE: Current measurement on high voltage dc line

    Hi shichen717,

    I have calculated Rsense in 4.7Ohm and I can use an ADC (ex. AD7789 with AIN(-) connected to AGND) without input buffer. Do you think I could have any problems on low voltage with such a resistor's value?

    Could you please send me…

  • RE: Looking for product longevity advice (Roadmap) with integration of Linear Tech

    Hi Phil,

       for ADC1 I can recommend to you one of the latest in the ADIs  SAR ADC portfolio, the AD4003 which I think fit the specification you've mentioned above.

       For ADC2 you can check the AD7789 or AD7791(on chip buffer). You may also try to have…
