    n 40-Pin (6mm Г— 6mm) QFN Package The LTCВ®2258-14/LTC2257-14/LTC2256-14 are sampling 14-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 74dB SNR and 88dB spurious
    free dynamic range (SFDR). Ultralow jitter of 0.17psRMS
    allows undersampling of IF frequencies with excellent
    noise performance. n DC specs include В±1LSB INL (typical), В±0.3LSB DNL (typical) and no missing codes over temperature. The transition ...
