PRODUCT HIGHLIGHTS

1. The AD9269 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. An optional SPI selectable dc correction and quadrature

error correction (QEC) feature corrects for dc offset, gain,

and phase mismatches between the two channels.

4. 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 timing

and offset adjustments, and voltage reference modes.

5. The AD9269 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 AD9251 14-bit ADC

the AD9231 12-bit ADC, the AD6659 12-bit baseband

diversity receiver, 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

Handheld scope meters

Portable medical imaging

Ultrasound

Radar/LIDAR
