The LTC®2172-12/LTC2171-12/LTC2170-12 are 4-channel, simultaneous sampling 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 71dB SNR and 90dB spurious free dynamic range (SFDR). An ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance. DC specifications include ±0.3LSB INL (typ), ±0.1LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.3LSBRMS. The digital outputs are serial LVDS to minimize the number o...
