ADS7028: CRC function

Part Number: ADS7028
Other Parts Discussed in Thread: ADS122U04

Hi all

Would you mind if we ask ADS7028?

We would like to understand ADS7028's CRC function.
Is this function for the data integrity of SPI transmission between ADC and CPU?
We image that it is similar with ADS122U04's one.
If we have some wrong, could you let us know?

Kind regards,

Hirotaka Matsumoto

  • Hello,

    Correct, the CRC is for data integrity between the ADC and CPU

    The method between the two devices are the similar, but there are differences in how the CRC code is calculated.

    the polynomial equation to calculate the CRC is different in each device.

    But, the method that the CRC is applied to the device and communications is the same

    Is there a specific question or concern regarding this?
