LTC2284

Dual 14-Bit, 105Msps

Low Power 3V ADC

FEATURES

DESCRIPTIO

The LTC^®2284 is a 14-bit 105Msps, low power dual 3V

A/Dconverterdesignedfordigitizinghighfrequency, wide

dynamic range signals. The LTC2284 is perfect for

demanding imaging and communications applications

with AC performance that includes 72.4dB SNR and 85dB

SFDR for signals at the Nyquist frequency.

■

Integrated Dual 14-Bit ADCs

■

Sample Rate: 105Msps

■

Single 3V Supply (2.85V to 3.4V)

■

Low Power: 540mW

72.4dB SNR, 88dB SFDR

■

110dB Channel Isolation at 100MHz

■

Flexible Input: 1V_P-Pto 2V_P-PRange

Typical DC specs include ±1.5LSB INL, ±0.6LSB DNL. The

■

575MHz Full Power Bandwidth S/H

transition noise is a low 1.3LSB_RMS

■

Clock Duty Cycle Stabilizer

■

A single 3V supply allows low power operation. A separate

output supply allows the outputs to drive 0.5V to 3.6V

logic.
