ADC081000
8-Bit, 1 GSPS A/D Converter with Internal Reference and
Sample-and-Hold
General Description
NOTE: This product is currently in development. - ALL
specifications are design targets and are subject to
change.
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 while consum-
ing a typical 1.4 Watts from a single 1.9 Volt supply at 1.0
GSPS. This device is guaranteed to have no missing codes
over the full operating temperature range. The unique
folding/interpolating architecture, the fully differential com-
parator design and the innovative design of the internal
sample-and-hold amplifier enable a very flat SINAD/ENOB
response beyond Nyquist, producing a high 7.5 ENOB with a
100 MHz input signal and a 1 GHz sample rate. Output
formatting is offset binary coding with LVDS digital outputs
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 and reduces 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 MSPS output rate per bus and a
combined output rate of 1 GSPS.
Setting the PD (Power Down) pin high places the converter
into an inactive power down state, where it typically con-
sumes less than 5 mW.
The ADC081000 is available in a 128-lead exposed pad
LQFP and operates over the industrial (-40
