1. The AD9609 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 and data output
(D9 to D0) timing and offset adjustments, and voltage
4. The AD9609 is packaged in a 32-lead RoHS compliant
LFCSP that is pin compatible with the AD9629 12-bit ADC
and the AD9649 14-bit ADC, enabling a simple migration
path between 10-bit and 14-bit converters sampling from
20 MSPS to 80 MSPS.
