LTC2251/LTC2250

10-Bit, 125/105Msps

Low Noise 3V ADCs

FEATURES

DESCRIPTIO

The LTC^®2251/LTC2250 are 10-bit 125Msps/105Msps,

low noise 3V A/D converters designed for digitizing high

frequency, wide dynamic range signals. The LTC2251/

LTC2250 are perfect for demanding imaging and commu-

nications applications with AC performance that includes

61.6dB SNR and 85dB SFDR for signals at the Nyquist

frequency.

■

Sample Rate: 125Msps/105Msps

■

Single 3V Supply (2.85V to 3.4V)

■

Low Power: 395mW/320mW

■

61.6dB SNR

85dB SFDR

No Missing Codes

■

Flexible Input: 1V_P-Pto 2V_P-PRange

■

640MHz Full Power Bandwidth S/H

DC specs include ±0.1LSB INL (typ), ±0.05LSB DNL (typ)

and ±0.6LSB INL, ±0.6LSB DNL over temperature. The

transition noise is a low 0.08LSB_RMS

■

Clock Duty Cycle Stabilizer

■

Shutdown and Nap Modes

■

Pin Compatible Family:

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

output supply allows the outputs to drive 0.5V to 3.3V

logic.

125Msps: LTC2251 (10-Bit), LTC2253 (12-Bit)

105Msps: LTC2250 (10-Bit), LTC2252 (12-Bit)

80Msps: LTC2239 (10-Bit), LTC2229 (12-Bit)

65Msps: LTC2238 (10-Bit), LTC2228 (12-Bit)

40Msps: LTC2237 (10-Bit), LTC2227 (12-Bit)

25Msps: LTC2236 (10-Bit), LTC2226 (12-Bit)

Asingle-endedCLKinputcontrolsconverteroperation.An

optional clock duty cycle stabilizer allows high perfor-

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