The LTC2222 and LTC2223 are 105Msps/80Msps, sampling 12-bit A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2222/LTC2223 are perfect for demanding communications applications with AC performance that includes 68dB 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 ±0.3LSB INL (typ), ±0.2LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.5LSBRMS.

A separate output power supply allows the outputs to drive 0.5V to 3.6V logic.

The ENC+ and ENC– inputs may be driven differentially or single ended with a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
