LTC2248/LTC2247/LTC2246

14-Bit, 65/40/25Msps

Low Power 3V ADCs

FEATURES

DESCRIPTIO

The LTC^®2248/LTC2247/LTC2246 are 14-bit 65Msps/

40Msps/25Msps, low power 3V A/D converters designed

for digitizing high frequency, wide dynamic range signals.

The LTC2248/LTC2247/LTC2246 are perfect for demand-

ing imaging and communications applications with AC

performance that includes 74.3dB SNR and 90dB SFDR

for signals at the Nyquist frequency.
