LTC2157-14/
LTC2156-14/LTC2155-14
Dual 14-Bit 250Msps/
210Msps/170Msps ADCs
FEATURES DESCRIPTION n n n n n n n n n n n The LTC®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
