General Description

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.
