The LTC2284 is perfect for demanding imaging and communications applications with AC performance that includes 72.4dB SNR and 85dB SFDR for signals at the Nyquist frequency. Typical DC specs include ±1.5LSB INL, ±0.6LSB DNL. The transition noise is a low 1.3LSBRMS. A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V 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....
