Hi,

  Can THS4551 be used to drive the inputs of ADS4222 adc ?

    Hi Vishak,

    If your input frequencies are lower and limited to less than 10MHz where the harmonic distortion starts degrading beyond -50dBc (see Figure 13 in the THS4551 datasheet), then it is possible to use the THS4551 for driving the ADS4222.

    If you are planning to provide input signals for the entire ADC spectrum, then I would rather suggest to use the THS4541. The advantage of using the THS4541 vs the THS4551 is that the anti-aliasing filter implementation for the THS4541 could be of lower order compared to the THS4551.

    Best Regards,
    Rohit
