LTC2298/LTC2297/LTC2296

Dual 14-Bit, 65/40/25Msps

Low Power 3V ADCs

FEATURES

DESCRIPTIO

The LTC^®2298/LTC2297/LTC2296 are 14-bit 65Msps/

40Msps/25Msps, low power dual 3V A/D converters de-

signed for digitizing high frequency, wide dynamic range

signals. The LTC2298/LTC2297/LTC2296 are perfect for

demanding imaging and communications applications

with AC performance that includes 74.3dB SNR and 90dB

SFDR for signals at the Nyquist frequency.

■

Integrated Dual 14-Bit ADCs

■

Sample Rate: 65Msps/40Msps/25Msps

■

Single 3V Supply (2.7V to 3.4V)

■

Low Power: 400mW/235mW/150mW

■

74.3dB SNR

90dB SFDR

■

110dB Channel Isolation at 100MHz

■

Multiplexed or Separate Data Bus

DC specs include ±1.2LSB INL (typ), ±0.5LSB DNL (typ)

■

Flexible Input: 1V_P-Pto 2V_P-PRange

and no missing codes over temperature. The transition

575MHz Full Power Bandwidth S/H

noise is a low 1LSB_RMS

■

Clock Duty Cycle Stabilizer

■

Shutdown and Nap Modes

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

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

logic. An optional multiplexer allows both channels to

share a digital output bus.
