    64-Pin (9mm Г— 9mm) QFN Package The LTCВ®2182/LTC2181/LTC2180 are two-channel simultaneous sampling 16-bit A/D converters designed for
    digitizing high frequency, wide dynamic range signals. They
    are perfect for demanding communications applications
    with AC performance that includes 77dB SNR and 90dB
    spurious free dynamic range (SFDR). Ultralow jitter of
    0.07psRMS allows undersampling of IF frequencies with ...
