Linear Technology LTC2251IUH#PBF

Description
The LTC2251/LTC2250 are 10-bit, 125Msps/105Msps, low noise 3V A/D converters designed for digitizing high-frequency, wide dynamic range signals. They are ideal for demanding imaging and communications 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 0.08LSBRMS.
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 performance at full speed for a wide range of clock duty cycles.
