ADC128S102EVM: ADS128S102

Part Number: ADC128S102EVM
Other Parts Discussed in Thread: ADC128S102

Hi! I would like to know the voltage scale for calibration? Calibration factor for ADC128S102EVM?

  • Hi Vichu,

    Welcome to TI's e2e Community.

    There are no internal calibration registers in the ADC128S102, I do not think the EVM is calibrated.

    The output codes in decimal are converted to voltage with the following formula:

    Vin = (ADC Code/4096)*VA.  The EVM board sets VA=3.3V by default,  You can use an external reference or supply from 2.7V to 5.25V as well.
