LTC2257IUJ-14#PBF

LTC®2257-14 is a 40Msps, ultra-low power 1.8V A/D converter designed for digitizing high frequency, wide dynamic range signals. 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 1.2V to 1.8V. Typical applications include communications, cellular base stations, software-define radios, portable medical imaging, multi-channel data acquisition, non-destructive testing.

• Selectable input range from 1VP-P to 2VP-P
• 800MHz full-power bandwidth S/H
• Optional data output randomizer and optional clock duty cycle stabilizer
• Shutdown and nap modes
• Serial SPI port for configuration
• Pin compatible 14bit and 12bit versions
• 40 lead QFN package
• Operating temperature range from -40°C to 85°C
