PRODUCT HIGHLIGHTS

1. The AD9648¹operates from a single 1.8 V analog

power supply and features a separate digital output

driver supply to accommodate 1.8 V CMOS or LVDS

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.

Radar/LIDAR

4. The AD9648 is packaged in a 64-lead RoHS compliant

LFCSP that is pin compatible with the AD9650/

AD9269/AD9268 16-bit ADC, the AD9258 14-bit

ADC, the AD9628/AD9231 12-bit ADCs, and the

AD9608/AD9204 10-bit ADCs, enabling a simple

migration path between 10-bit and 16-bit converters

sampling from 20 MSPS to 125 MSPS.
