FEATURES DESCRIPTION n n n n n n n n n n n The LTC®2157-12/LTC2156-12/LTC2155-12 are a family of
dual 250Msps/210Msps/170Msps 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 68.5dB
SNR and 90dB spurious free dynamic range (SFDR). The
1.25GHz input bandwidth allows the ADC to achieve high
undersampling ratio with very low attenuation. The latency
is only six clock cycles. n 68.5dB SNR
