• RE: What is AD7190 minimum AVDD voltage? The data sheet shows 4.75Vdc.  Can I use 3.3Vdc as AVDD if I am using 2.5Vdc reference?


    The evaluation board is used for AD7190 and AD7192 part. The AD7192 can operate from 3V to 5.25V. So the option for 3.3V is for AD7192 part.

  • RE: What order has the delta sigma converter in AD7192 ?

    Hi Kenneth43,

    The AD7192 uses a fourth order modulator. The filter is either sinc3 or sinc4 - you can choose which option to use via the SINC3 bit.

    The AD7192 uses standard sinc3 and sinc4 filters. Review the excel file on the AD7192 product page …

  • RE: AD7192 x2 and x4 gain


         The AD7192 can still function at  gain of 2 and 4. When Vref is 2.5V, the AD7192 does not guarantee to meet the specification at gain 2 and 4. These gains are not specified on the datasheet.
