LTC2246H

14-Bit, 25Msps

125°C ADC In LQFP

FEATURES

DESCRIPTION

The LTC^®2246H is a 14-bit 25Msps, low power 3V A/D

converter designed for digitizing high frequency, wide

dynamic range signals. The LTC2246H is perfect for

demanding imaging and communications applications

with AC performance that includes 74.5dB SNR and 90dB

SFDR.

Sample Rate: 25Msps

–40°C to 125°C Operation

Single 3V Supply (2.8V to 3.5V)

Low Power: 75mW
