    Hello Chen,

    Yes, the ADS127L21 is a good option verses the AD7766.  The ADS127L21 is a delta-sigma topology where the AD7766 is an oversampling SAR.

    The ADS127L21 has a wide range of filter options, including wideband (brickwall) filter and low latency SINC filters. 

    A few of the key specifications:

    Wide dynamic range (SINC4 filter, MAX speed mode)

    110.9dB dynamic range at 512ksps

    123.3dB dynamic range at 32ksps

    Low Power

    14mW at 200ksps

    4.3mW at 50ksps

    High DC accuracy

    INL: 0.4 ppm of FS (typical)

    Offset drift: 50 nV/°C (typical)

    Gain drift: 0.5 ppm/°C (typical)
