PRODUCT HIGHLIGHTS

The AD9204 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 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.

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.

The AD9204 is packaged in a 64-lead RoHS compliant

LFCSP that is pin compatible with the AD9268 16-bit

ADC, the

AD9251

and

AD9258

14-bit ADCs, and the

AD9231

12-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

Handheld scope meters

Ultrasound

Radar/LIDAR

PET/SPECT imaging
