DESCRIPTION

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 1.9 Watts at 3

GSPS from a single 1.9 Volt supply, this device is

specified 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 selfAPPLICATIONS

calibration scheme enable an excellent 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 Word Error Rate. 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 compatible with IEEE 1596.3-1996,

with the exception of an adjustable common mode

voltage between 0.8V and 1.15V.

The 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 converter typically consumes less than 25 mW in

the Power Down Mode and is available in a 128-lead,

thermally enhanced exposed pad HLQFP and

operates over the Industrial (-40°C ≤ TA ≤ +85°C)

temperature range.
