40-Pin (6mm × 6mm) QFN Package The LTC®2265-14/LTC2264-14/LTC2263-14 are 2-channel,
simultaneous 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 73.7dB SNR and
90dB spurious free dynamic range (SFDR). Ultralow jitter
of 0.15psRMS allows undersampling of IF frequencies with
excellent noise performance. …
