ADC081500
High Performance, Low Power, 8-Bit, 1.5 GSPS A/D
Converter
General 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 guaranteed to have no missing codes over the full
operating temperature range. The unique folding and inter-
polating architecture, the fully differential comparator design,
the innovative design of the internal sample-and-hold ampli-
fier and the self-calibration scheme enable a very flat re-
sponse of all dynamic parameters beyond Nyquist, produc-
ing 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
compliant with IEEE 1596.3-1996, with the exception of an
adjustable common mode 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 LQFP and operates over the Indus-
trial (-40˚C TA +85˚C) temperature range.
