LTC2220/LTC2221 12-Bit,170Msps/ 135Msps ADCs DESCRIPTIO The LTC®2220 and LTC2221 are 170Msps/135Msps, sampling 12-bit A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2220/ LTC2221 are perfect for demanding communications applications with AC performance that includes 67.5dB SNR and 80dB spurious free dynamic range for signals up to 170MHz. Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance. DC specs include ±0.4LSB INL (typ), ±0.3LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.5LSBRMS. The digital outputs can be ...
