ADC08B3000 High Performance, Low Power, 8-Bit, 3 GSPS A/D Converter with 4K Buffer General Description Note: This product is currently in development. - ALL specifications are design targets and are subject to change. The ADC08B3000 is a single, low power, high performance CMOS analog-to-digital converter that digitizes signals to 8 bits resolution at sampling rates up to 3.4 GSPS. Consuming a typical 1.8 Watts at 3 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 upto Nyquist, pro- ducing a high 7.0 ENOB with a 748 MHz input signal and a 3 GHz sample rate while providing a 10 -18 B.E.R. 3 GSPS is achieved through using a 1.5GHz clock. Output formatting is offset binary. The device contains a 4K FIFO Capture Buffer which is used to feed two 8 bit CMOS output busses at a rate up to 200MHz. The converter typically consumes less than 20 mW in the Power Down Mode and is available in a 128-lead, thermally enhanced exposed pad LQFP and operates over the Indus- trial (-40˚C ≤ T A ≤ +85˚C) temperature range.
