    FEATURES DESCRIPTION n n n n n n n n n n n The LTCВ®2157-14/LTC2156-14/LTC2155-14 are 2-channel
    simultaneous sampling 250Msps/210Msps/170Msps
    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 70dB SNR and 90dB spurious
    free dynamic range (SFDR). The 1.25GHz input bandwidth
    allows the ADC to undersample high frequencies with
    good performance. The latency is only six clock cycles. n 70dB SNR
    90dB SFDR
