DESCRIPTION
The ADC081500 is a low power, high performance
CMOS analog-to-digital converter that digitizes
signals to 8 bits resolution at sample rates up to 1.7
GSPS. Consuming a typical 1.2 W at 1.5 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 7.3 ENOB with a 748 MHz input signal and a 1.5
GHz sample rate while providing a 10-18 B.E.R.
Output formatting is offset binary and the LVDS
digital outputs are compatible with IEEE 1596.3-1996,
with the exception of an adjustable output offset
voltage between 0.8V and 1.2V.
The converter output has a 1:2 demultiplexer that
feeds two LVDS buses and reduces the output data
rate on each bus to one-half the sample rate.
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 HLQFP and
operates over the Industrial (-40°C TA +85°C)
temperature range.
