PRODUCT HIGHLIGHTS

1. The AD9649 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 (SPI) supports various

product features and functions, such as data output format-

ting, internal clock divider, power-down, DCO, data output

(D13 to D0) timing and offset adjustments, and voltage

reference modes.

4. The AD9649 is packaged in a 32-lead RoHS-compliant LFCSP

that is pin compatible with the AD9629 12-bit ADC and

the AD9609 10-bit ADC, enabling a simple migration path

between 10-bit and 14-bit converters sampling from 20 MSPS

to 80 MSPS.

APPLICATIONS
