PRODUCT HIGHLIGHTS 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 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 reference modes.
4.
The AD9609 is packaged in a 32-lead RoHS compliant LFCSP that is pin compatible with the AD9629 12-bit ADC and ...
