Dual 10-bit, 200 MSPS Low-Power A/D Converter with
Parallel LVDS/CMOS Outputs
General Description
The ADC10DV200 is a monolithic analog-to-digital converter
capable of converting two analog input signals into 10-bit dig-
ital words at rates up to 200 Mega Samples Per Second
(MSPS). The digital output mode is selectable and can be ei-
ther differential LVDS or CMOS signals. This converter uses
a differential, pipelined architecture with digital error correc-
tion and an on-chip sample-and-hold circuit to minimize die
size and power consumption while providing excellent dy-
namic performance. A unique sample-and-hold stage yields
a full-power bandwidth of 900MHz. Fabricated in core CMOS
process, the ADC10DV200 may be operated from a single
1.8V power supply. The ADC10DV200 achieves approxi-
mately 9.6 effective bits at Nyquist and consumes just 280mW
at 170MSPS in CMOS mode and 450mW at 200MSPS in
LVDS mode. The power consumption can be scaled down
further by reducing sampling rates.
