[FAQ] ADS1258 / ADS1158: What is the output data format and LSB size?

Other Parts Discussed in Thread: ADS1158, ADS1258

What is the output data format and LSB size of the ADS1258 or ADS1158 devices? 

  • For assistance in scaling the ADS1x58 output data, here is the data formatting table and equation for the LSB size:

    NOTE:

    The output codes from the ADS1x58 are 2's compliment (signed) values. 24-bit signed for the ADS1258, and 16-bit signed for the ADS1158.
    Therefore, 0xFFFFFF (hex) = -1 (decimal) for the ADS1258, and 0xFFFF (hex) = -1 (decimal) for the ADS1158.
