ADS8887: ADS8887 multiple data resister read

Iwata Etsuji

Part Number: ADS8887

Hi team,

Can we read the same data resister value of ADS8887 in multiple-times if we would not issue CONVST during multiple reading?

Best regards,

Hello Etsuji-san,

The ADS888x family does not support multiple reading of the data. After the 18th SCLK falling edge, DOUT will go to Hi-Z and stay in this state until the next conversion cycle is complete and new data are available to be read out of the device.
