ADC08D1000

High Performance, Low Power, Dual 8-Bit, 1 GSPS A/D

Converter

General Description

Features

n Internal Sample-and-Hold

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 1.3 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 ENOB with a 500 MHz input signal and

a 1 GHz sample rate while providing a 10^-18B.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.

n Single +1.9V 0.1V Operation

n Choice of SDR or DDR output clocking

n Interleave Mode for 2x Sampling Rate

n Multiple ADC Synchronization Capability

n Guaranteed No Missing Codes

n Serial Interface for Extended Control

n Fine Adjustment of Input Full-Scale Range and Offset

n Duty Cycle Corrected Sample Clock

n Max Conversion Rate

n Bit Error Rate

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.

n Power Consumption

— Operating

1.6 W (typ)

3.5 mW (typ)

The converter typically consumes less than 3.5 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.
