How to make ADS129x inputs low ?

It is mentioned in ADS129x datasheet in page 42 (power-up sequencing) that all digital and analog inputs must be low . How should I do this ?

  • Hello Hamed,

    On the digital side it is simply a matter of ensuring all the digital inputs to the ADS129x are at logic low levels at startup. On the analog side, just try to make sure your supplies are ramping faster than your inputs. Is your application such that the analog inputs would be at a high level before power up?
