DESCRIPTION
The ADC11DV200 is a monolithic analog-to-digital
converter capable of converting two analog input
signals into 11-bit digital words at rates up to 200
Mega Samples Per Second (MSPS). The digital
output mode is selectable and can be either
differential LVDS or CMOS signals. This converter
uses a differential, pipelined architecture with digital
error correction and an on-chip sample-and-hold
circuit to minimize die size and power consumption
while providing excellent dynamic performance. A
unique sample-and-hold stage yields a full-power
bandwidth of 900MHz. Fabricated in core CMOS
process, the ADC11DV200 may be operated from a
single 1.8V power supply. The ADC11DV200
achieves approximately 10.06 effective bits at Nyquist
and consumes just 280mW at 170MSPS in CMOS
mode 450mW at 200MSPS in LVDS mode. The
power consumption can be scaled down further by
reducing sampling rates.
