PRODUCT HIGHLIGHTS

1. The AD9251 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 supports various product

features and functions, such as data output formatting,

internal clock divider, power-down, DCO/DATA timing

and offset adjustments, and voltage reference modes.

4. The AD9251 is packaged in a 64-lead RoHS compliant

LFCSP that is pin compatible with the AD9268 16-bit

ADC, the AD9258 14-bit ADC, the AD9231 12-bit ADC,

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.

APPLICATIONS

Communications

Diversity radio systems

Multimode digital receivers

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

I/Q demodulation systems

Smart antenna systems

Battery-powered instruments

Hand held scope meters

Portable medical imaging

Ultrasound

Radar/LIDAR
