ADS9226: Data Conversion and SCLK

Russell Wetherley1

Part Number: ADS9226

Hello E2E,

I hope you can shore up my understanding on the ADS9226 and how many SCLK pulses are needed to complete a conversion.  Looking at 7.4.4, is it a little unclear to me what impacts this number and how many clock pulses are needed to implement and complete a conversion.

Thanks!

Russell

    Hi Russel,

    It looks like 8 SCLKs to me. SDO-1x gives even bits and SDO-0x gives odd bits. Something like:

    N = resolution = 16 bits

    • SCLK   : 1   2   3   4    5  6  7  8 
    • SDO-1x: 16 14 12 10 8  6  4  2
    • SDO-0x: 15 13 11 9   7  5  3  1

    Though, the diagrams show starting from 0.

    Best,
