PRODUCT HIGHLIGHTS
1.
Operates from a single 1.8 V analog power supply and
features a separate digital output driver supply to accom-
modate 1.8 V CMOS or 1.8 V LVDS logic families.
2.
Provides a patented sample-and-hold circuit that maintains
excellent performance for input frequencies up to 200 MHz
and is designed for low cost, low power, and ease of use.1
3.
Includes a standard serial port interface that supports various
product features and functions, such as data output format-
ting, internal clock divider, power-down, DCO/data timing,
and offset adjustments.
4.
Packaged in a 64-lead, RoHS-compliant LFCSP that is pin
compatible with the AD9650, AD9269, and AD9268 16-bit
ADCs, the AD9258 and AD9648 14-bit ADCs, the AD9628
and AD9231 12-bit ADCs, 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.
