32-Pin (5mm

5mm) QFN Package

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.

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

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

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

logic.

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.
