PRODUCT HIGHLIGHTS

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.

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.

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.

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.

APPLICATIONS

Communications

Diversity radio systems

Multimode digital receivers

GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX, TD-SCDMA

Smart antenna systems

Battery-powered instruments

Handheld scope meters

Portable medical imaging

Ultrasound

Radar/LIDAR

PET/SPECT imaging
