Features Total Ionizing Dose 300 krad(Si) Single Event Latch-Up >120 MeV/mg/cm 2 Internal Sample-and-Hold Single +1.9V ±0.1V Operation Choice of SDR or DDR output clocking Interleave Mode for 2x Sampling Rate Multiple ADC Synchronization Capability Guaranteed No Missing Codes Serial Interface for Extended Control Fine Adjustment of Input Full-Scale Range and Offset Duty Cycle Corrected Sample Clock Description The ADC08D1000 is a dual, low power, high performance CMOS analog-to-digital converter that digitizes signals to 8 bits resolution at sampling rates up to 1.2 GSPS. Consuming a typical 1.6 Watts at 1 GSPS from a single 1.9 Volt supply, this device is guaranteed to have no missing codes over the full operating temperature range. The unique folding and interpolating architecture, the fully differential comparator design, the innovative design of the internal sample-and-hold amplifier and the self-calibration scheme enable a very flat response of all dynamic parameters beyond Nyquist, producing a high 7.4 Effective Number Of Bits (ENOB) with a 498 MHz input signal and a 1 GHz sample rate while providing a 10 -18 Bit Error Rate ( B.E.R.). Output formatting is offset binary and the Low Voltage Differential Signaling (LVDS) digital outputs are compliant with IEEE 1596.3-1996, with the exception of an adjustable common mode voltage between 0.8V and 1.13V. Each converter has a 1:2 demultiplexer that feeds two LVDS buses and reduces the output data rate on each bus to half the sampling rate. The two converters can be interleaved and used as a single 2 GSPS ADC. The converter typically consumes less than 3.5 mW in the Power Down Mode and is available in a 128-lead, thermally enhanced multi-layer ceramic quad package and operates over the Military (-55°C ≤ TA ≤ +125°C) temperature range. This part will work in a radiation environment, with excellent results, provided the guidelines in applications section 2.1 are followed .
