LTC2255CUH#PBF

LTC2255 is a 14bit 125Msps, low power 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding imaging and communications applications with AC performance that includes 72.3dB SNR and 85dB SFDR for signals at the Nyquist frequency. 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. It is used in applications such as wireless and wired broadband communication, imaging systems, ultrasound, spectral analysis, portable instrumentation.
