  • Hello Songzhen,

    Thanks for the question, we'll definitely be able to help on this. Let me talk with the team and get you a response around Wednesday or Thursday of next week. I apologize for the delay, there's a holiday this Monday in the US and a lot of people are taking time off right now. I ask for you and the customer's patience.

    Thank you,


  • Hi Songzhen,

    Thanks for your question. The total time between analog input and digital data output will be the time taken for /DRDY low to transition high and then low again. This is also equal to the reciprocal of the user-programmed data rate. The data rate can be programmed by the user to be 8, 16, 32, 64, 128, 250, 475, or 860 SPS.

    Best regards,
