The ADC08D1020 is a dual, low power, high performance,CMOS analog-to-digital converter that builds upon the ADC08D1000platform. The ADC08D1020 digiTIzes signals to 8bits of resoluTIon at sample rates up to 1.3 GSPS. It has expandedfeatures compared to the ADC08D1000, which includea test pattern output for system debug, a clock phaseadjust, and selectable output demulTIplexer modes. Consuminga typical 1.6 Watts in non-demulTIplex mode at 1 GSPSfrom a single 1.9 Volt supply, this device is guaranteed to haveno missing codes over the full operating temperature range.The unique folding and interpolating architecture, the fully differentialcomparator design, the innovative design of the internalsample-and-hold amplifier and the calibration schemesenable a very flat response of all dynamic parameters beyondNyquist, producing a high 7.4 Effective Number of Bits(ENOB) with a 498 MHz input signal and a 1 GHz sample ratewhile providing a 10−18 Code Error Rate (C.E.R.) Output formattingis offset binary and the Low Voltage Differential Signaling(LVDS) digital outputs are compatible with IEEE1596.3-1996, with the exception of an adjustable commonmode voltage between 0.8V and 1.2V.
