ADS8584S: ADS8584S reset pin circuitry

Part Number: ADS8584S

As per the datasheet of ADS8584S reset pin requires a rising edge after power up.

 

Actually I don’t need a any control for RESET. So that I tied RESET pin to low.

Whether it is OK? Or we need to consider any circuitry for single pulse after power up?

 

Thanks and Regards

  • The reset pin was added to provide you with the flexibility to reset the system in the case of an abnormal power up condition, supply brown out condition, or supply glitch. These kinds of events are rare, but we require that you connect the RESET pin to your controller to and always reset the device after power-up as well as after recovery from shut-down mode to avoid issues.

    For more information see the ADS8584S data sheet section on Reset:

    The device must always be reset after power-up as well as after recovery from shut-down mode when all the supplies and references have settled to the required accuracy. If the RESET is issued during an ongoing conversion process, then the device aborts the conversion and output data are invalid. If the reset signal is applied during a data read operation, then the output data registers are all reset to zero.

    best regards,
