n 40-Pin (6mm × 6mm) QFN Package The LTC®2261-12/LTC2260-12/LTC2259-12 are 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 70.8dB SNR and 85dB spurious
free dynamic range (SFDR). Ultralow jitter of 0.17psRMS
allows undersampling of IF frequencies with excellent
noise performance. n Applications n n n n Communications …
