Part Number: ADS7924

Hi,

I am looking for the timing requirements for a reset pulse using the external reset pin on ADS7924. I can not see this information listed in the datasheet.

Thanks

Simon

  • Simon,


    I've checked with a colleague and someone here had done some basic tests on the RESET pin in the past.

    The RESET pin is falling edge triggered and they were able to get a RESET on a pulse as narrow as 20ns. After the reset, it takes about 60ns for the device to come out of reset.

    However after the reset, it is recommended to wait 2us before issuing a command. This is based on a recommendation from the ADS8332 datasheet which has similar reset circuity.
