ADC08D1000
High Performance, Low Power, Dual 8-Bit, 1 GSPS A/D
Converter
General Description
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
-18 B.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.
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.
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

A
≤ +85˚C) temperature range.
