1. On-chip dither option for improved SFDR performance

with low power analog input.

2. Proprietary differential input that maintains excellent SNR

performance for input frequencies up to 300 MHz.

3. Operation from a single 1.8 V supply and a separate digital

output driver supply accommodating 1.8 V CMOS or

LVDS outputs.

4. Standard serial port interface (SPI) that supports various

product features and functions, such as data formatting

(offset binary, twos complement, or gray coding), enabling

the clock DCS, power-down, test modes, and voltage

reference mode.

5. Pin compatibility with the AD9258, allowing a simple

migration from 16 bits to 14 bits. The AD9268 is also pin

compatible with the AD9251, AD9231, and AD9204 family

of products for lower sample rate, low power applications.
