LTC2144-12/LTC2143-12
12-Bit, 125Msps/105Msps/
80Msps Low Power Dual ADCs
FEATURES DESCRIPTION n The LTC®2145-12/LTC2144-12/LTC2143-12 are 2-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 70.6dB SNR and
89dB spurious free dynamic range (SFDR). Ultralow jitter
of 0.08psRMS allows undersampling of IF frequencies with
excellent noise performance. 2-Channel Simultaneously Sampling ADC
