ADS1115: Step Response

Hi Team,

    How is ADS1115's Step Response looks like? That means how many sample/cycles are needed from a step of 0V - 1V? And what's the filter type, sinc3?

    Thanks.

    Holly,

    The ADS1115 is single-cycle settling. This is similar to a sinc1 filter.

    For the step response, if the step occurs at exactly the start of a conversion cycle, then the data you get at the end of the conversion cycle is settled.
