ADS1298: Help in converting ADC code

Andrew M

Part Number: ADS1298

Good morning all,

For the system that is operated at +-3 V with the reference on the ground, how do I convert the ADC code (after the 24bit 2's complement form conversion) to the corresponding output voltage?

Thanks,

Andrew

Hi Andrew,

Welcome to our e2e fourm! Please refer to the ADS1298 datasheet, page 54, section 9.4.1.3.3 and Table 13 for the general representation of input voltage to output code. The maximum input range to the ADS1298 is +/- Vref / Gain.
