LTC2256IUJ-14#PBF

LINEAR TECHNOLOGY LTC2256IUJ-14#PBF Analog to Digital Converter, 14Bit, 25MSPS, Single, 1.7V, 1.9V, QFN

The is a 14-bit ultralow power sampling Analog-to-digital Converter ADC designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding communications applications with AC performance that includes 74dB SNR and 88dB spurious free dynamic range SFDR. Ultralow jitter of 0.17psRMS allows under-sampling of IF frequencies with excellent noise performance. The digital outputs can be either full rate CMOS, double data rate CMOS or double data rate LVDS. A separate output power supply allows the CMOS output swing to range from 1.2 to 1.8V. 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.
