LTC2245

14-Bit, 10Msps

Low Power 3V ADC

FEATURES

DESCRIPTIO

The LTC^®2245 is a 14-bit 10Msps, low power 3V A/D

converter designed for digitizing high frequency, wide

dynamic range signals. The LTC2245 is perfect for de-

manding imaging and communications applications with

AC performance that includes 74.4dB SNR and 90dB

SFDR for signals well beyond the Nyquist frequency.
