General Description

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.
