    Do I need to connect power to both Vdd1 pins, Pin 1 and Pin7?

  • About AD7403 spec

    Hi there,

    I have a question about AD7403,  New Isolation ADC.

    Does AD7403  improve analog specs compared to AD7401A?

    What are the highlights of  AD7403 compared to AD7401A?

    Best regards,

    The customer has a question.

    They found EVAL-AD7403FMCZ user guide. But they couldn't find out EVAL-AD7403-8FMCZ user guide.

    I guess EVAL-AD7403-8FMCZ would be the Eval board for AD7403-8BRIZ.

    Could you let me know how to get the user guide…

  • Why has the power consumption of the AD7403 increased when compared to the AD7401A? 17mA typical at 20MHz and Vdd1 = 5.5V for the AD7401A and 42mA typical for the same conditions for the AD7403

    There are a few factors to consider that leads to the increased current consumption. The AC and DC performance of the AD7403 is much better in the AD7403 when compared to the AD7401A. For example the minimum SINAD for the AD7401A is 72dB however the…

  • RE: what's the maximum frequency of input signals for AD7403

    Hi zhouyan.

    AD7403 is specified at 1Khz input voltage. May I know what specific signal frequency you want to operate? We have a  Virtual Eval on ADI site that may help you evaluate and understand the performance of the AD7403 with any signal frequency…

  • RE: 2KV High-side, low-current measurement

    Hello Andy,

    ADI has a family of isolated S-D ADCs tailored for current monitoring. The newest device is the AD7403. If the high-side voltage is a DC level then the isolation provided by the AD7403 should be adequate. This would be simpler, smaller and…

  • (AD740*)What is the difference between AD7400 & AD7401 & AD7402 &AD7403?

    Hi !

    Our customer have interesting in AD740*.

    And they want know what is the difference between AD7400 & AD7401 & AD7402 & AD7403.

    Can you explain the difference?
