ADS9224R: max sampling rate of ADS9224R

Part Number: ADS9224R
Other Parts Discussed in Thread: ADS9234R,


I would like to confirm if the max sampling rate of 16 bits resolution for each channel of ADS9224R is 3Msps independently. How about ADS9234R?


  • Hi Jerry,

    Thank you for your post.

    The ADS9224R and ADS9234R can both sample up to 3 MSPS simultaneously. The ADS9224R has 16-bit resolution and the ADS9234R has 14-bit resolution.

    The enhanced-SPI digital interface offers three options for reducing the required SCLK speed for complete data transfer: 

    1. Increase the width of the output data bus (dual SDO, quad SDO, or parallel byte)
    2. Enable double data rate (DDR) transfer
    3. Extend the data transfer window to widen the read cycle.

    For more information, please refer to the Data Transfer Protocols section. Let me know if you have any addition questions.

    Best regards,
