DESCRIPTION
The LTC®2195/LTC2194/LTC2193 are 2-channel, simultaneous sampling 16-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 76.8dB SNR and 90dB spurious free dynamic range (SFDR). Ultralow jitter of 0.07psRMS allows undersampling of IF frequencies with excellent noise performance.
