LTC2255/LTC2254
14-Bit, 125/105Msps Low Power 3V ADCs
DESCRIPTIO
The LTC®2255/LTC2254 are 14-bit 125Msps/105Msps, low power 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2255/ LTC2254 are perfect for demanding imaging and munications applications with AC performance that includes 72.3d B SNR and 85d B SFDR for signals at the Nyquist frequency.
DC specs include ±1LSB INL (typ), ±0.5LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 1.3 LSBRMS.
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.
