LTC2281

Dual 10-Bit, 125Msps

Low Power 3V ADC

FEATURES

DESCRIPTION

The LTC^®2281 is a 10-bit 125Msps, low power dual 3V

A/D converter designed for digitizing high frequency,

wide dynamic range signals. The LTC2281 is perfect for

demanding imaging and communications applications

with AC performance that includes 61.6dB SNR and 82dB

SFDR for signals at the Nyquist frequency.

Integrated Dual 10-Bit ADCs

Sample Rate: 125Msps

Single 3V Supply (2.85V to 3.4V)

Low Power: 790mW

61.6dB SNR, 88dB SFDR

110dB Channel ꢀsolation at 100MHz

Flexible ꢀnput: 1V to 2V Range

P-P

Typical DC specs include 0.1LSB ꢀNL, 0.1LSB DNL. The

transition noise is a low 0.08LSB

640MHz Full Power Bandwidth S/H

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.

Shutdown and Nap Modes

Data Ready Output Clock

Pin Compatible Family

125Msps: LTC2283 (12-Bit), LTC2281 (10-Bit)

105Msps: LTC2282 (12-Bit), LTC2280 (10-Bit)

80Msps: LTC2294 (12-Bit), LTC2289 (10-Bit)

65Msps: LTC2293 (12-Bit), LTC2288 (10-Bit)

40Msps: LTC2292 (12-Bit), LTC2287 (10-Bit)

64-Pin (9mm × 9mm) QFN Package

A single-ended CLK input controls converter operation.

An optional clock duty cycle stabilizer allows high perfor-

mance at full speed for a wide range of clock duty cycles.

A data ready output clock (CLKOUT) can be used to latch

the output data.
