ADS1274: ADS1274 Dout

Part Number: ADS1274
Other Parts Discussed in Thread: ADS1278

Hi team,

Good day.

According to the datasheet, ADS1274: DOUT[8:5] Internally connected to active circuitry; outputs are driven. To what voltage levels are these outputs driven, and what is on these lines? Is the ADS1274 can be directly used to replace the ADS1278?

Regards,
Carlo

  • Hello,

    The note means that these pins are still connected to the same output buffers that are used in the ADS1278 when those pins are used for the output data.  Since there are only 4 ADCs in the ADS1274 nothing feeds those output buffers and they'll either drive to the Voh or Vol levels defined in the datasheet.  

    Yes, the ADS1274 can be directly used to replace the ADS1278.
