PRODUCT HIGHLIGHTS
1.
The AD9251 operates from a single 1.8 V analog power
supply and features a separate digital output driver supply
to accommodate 1.8 V to 3.3 V logic families.
2.
The patented sample-and-hold circuit maintains excellent
performance for input frequencies up to 200 MHz and is
designed for low cost, low power, and ease of use.
3.
A standard serial port interface supports various product
features and functions, such as data output formatting,
internal clock divider, power-down, DCO/DATA timing
and offset adjustments, and voltage reference modes.
4.
The AD9251 is packaged in a 64-lead RoHS compliant
LFCSP that is pin compatible with the AD9268 16-bit
ADC, the AD9258 14-bit ADC, the AD9231 12-bit ADC,
and the AD9204 10-bit ADC, enabling a simple migration
path between 10-bit and 16-bit converters sampling from
20 MSPS to 125 MSPS.
