The ADC083000 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 up to Nyquist, producing a high 7.0 Effective Number Of Bits, (ENOB) with a 748 MHz input signal and a 3 GHz sample rate while providing a 10-18 Bit Error Rate, (BER). The ADC083000 achieves a 3 GSPS sampling rate by utilizing both the rising and falling edge of a 1.5 GHz input clock. 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.

The ADC083000 ADC has a 1:4 demultiplexer that feeds four LVDS buses and reduces the output data rate on each bus to a quarter of the sampling rate. The ADC can be programmed into the 1:2 Output Mode where the data is output on the Dc and Dd channels at the rate of the input clock.

The ADC083000 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 Industrial (-40°C T_A +85°C) temperature range.
