  • About AD7401A

    Hi there,

     

    I have a question about AD7401

    Is it okay to connect Pin4  to GND?

    If it's connect to GND, what would happen?

    *According to the datasheet, it says Pini4 to 6 treated as NC(Non connect)

  • AD7401A

    Hi there,

    I have a question about the isolated-ADC

    Currently AMC1305Mx(CMOS) is used on the board.

    It looks like AD7401A is pin-compatible with it.

    Are there any concerens when we will replace AMC1305Mx with AD7401A?

    I noticed that pin1 is a bit…

  • Isolated Sigma-Delta Modulator AD7401A

    Hi ,

    I have a question here.I was just going through the AD7401A data sheet. And trying to implement the second order delta modulator. From the Page 14 of the AD7401A data sheet theere is a statement saying that "

    The analog input signal is continuously…

  • Using AD7401A with SINC4 Filter with Decimation Factor 128?

    In order to increase the bandwitdh and the SNR of the acquired data we would like to use a SINC4 Filter with a decimation factor 128 instead of a SINC3 Filter with a decimation factor 256. With these measures we hope to increase the bandwidth to 150 kHz…

  • 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?

  • RE: Watchdog of AD740x  series

    Hi Terumasa,

       I just had it confirmed, the watchdog is normally found on standard digital isolators but not on the AD7401A. Regarding the next question, when VDD1 is off, this means something happen on the hot side, the cold side(secondary) will retain…
