ADC08D500

High Performance, Low Power, Dual 8-Bit, 500 MSPS A/D

Converter

General Description

Features

The ADC08D500 is a dual, low power, high performance

CMOS analog-to-digital converter that digitizes signals to 8

bits resolution at sampling rates up to 800 MSPS. Consuming

a typical 1.4 Watts at 500 MSPS 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 in-

terpolating architecture, the fully differential comparator de-

sign, 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, produc-

ing a high 7.5 ENOB with a 250 MHz input signal and a 500

MHz sample rate while providing a 10^-18B.E.R. Output for-

matting 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 1.2V.

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 1 GSPS ADC.

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.
