n 52-Pin (7mm × 8mm) QFN Package The LTC®2172-12/LTC2171-12/LTC2170-12 are 4-channel,
simultaneous sampling 12-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 71dB SNR and 90dB
spurious free dynamic range (SFDR). An ultralow jitter of
0.15psRMS allows undersampling of IF frequencies with
excellent noise performance. n DC specifications include ±0.3LSB INL (typ), ±0.1LSB …
