The ADC08D1020 is a Low-Power, 8-Bit, Dual 1.0 GSPS or Single 2.0 GSPS A/D Converter
ADC08D1020 Product Folder Description:
The ADC08D1020 is a dual, low power, high performance CMOS analog-to-digital converter that builds upon the ADC08D1000 platform. It digitizes signals to 8 bits resolution at sample rates up to 1.3 GSPS. The ADC08D1020 has expanded features compared to the ADC08D1000, which include a test pattern output for system debug, a clock phase adjust, and selectable output demultiplexer modes. Consuming a typical 1.6 Watts in non-demultiplex mode 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 calibration schemes enable a very flat response of all dynamic parameters beyond Nyquist, producing a high 7.4 ENOB with a 498 MHz input signal and a 1 GHz sample rate while providing a 10-18 C.E.R. Output formatting is offset binary and the LVDS digital outputs are compliant with IEEE 1596.3-1996, with the exception of an adjustable common mode voltage between 0.8V and 1.2V.
Each converter has a selectable output demultiplexer which feeds two LVDS buses. If the 1:2 demultiplexed mode is selected, the output data rate on each bus is reduced to half the input sample 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 leaded or lead-free 128-lead, thermally enhanced exposed pad LQFP and operates over the Industrial (-40°C <= TA <= +85°C) temperature range.
