Description

General part information

LTC2254 Series

The LTC2255/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 communications applications with AC performance that includes 72.3dB SNR and 85dB 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.ApplicationsWireless and Wired Broadband CommunicationImaging SystemsUltrasoundSpectral AnalysisPortable Instrumentation
