The ADC3660 device is a low-noise, ultra-low power,16-bit, 65-MSPS dual-channel, high-speed analog-todigitalconverter (ADCs). Designed for low powerconsumption, the device delivers a noise spectraldensity of –159 dBFS/Hz, combined with excellentlinearity and dynamic range. The ADC3660 offersexcellent dc precision, together with IF samplingsupport, which make the device an excellent choicefor a wide range of applications. The ADC consumesonly 71 mW/ch at 65 MSPS, and power consumption

scales very well with lower sampling rates. In bypassmode (up to 31 MSPS) the output data is availableafter 1 or 2 clock cycles...
