DESCRIPTION
The ADC081000 is a low power, high performance
CMOS analog-to-digital converter that digitizes
signals to 8 bits resolution at sampling rates up to
1.6 GSPS. Consuming a typical 1.4 Watts at 1 GSPS
from a single 1.9 Volt supply, this device is ensured
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 7.5 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 a reduced common mode
voltage of 0.8V.
The converter has a 1:2 demultiplexer that feeds two
LVDS buses, reducing the output data rate on each
bus to half the sampling rate. The data on these
buses are interleaved in time to provide a 500 MHz
output rate per bus and a combined output rate of
1 GSPS.
The converter typically consumes less than 10 mW in
the Power Down Mode and is available in a 128-lead
HLQFP and operates over the industrial (–40°C ≤
T_A ≤ +85°C) temperature range.
