PRODUCT HIGHLIGHTS
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 AD9268, allowing a simple
migration from 14 bits to 16 bits. The AD9258 is also pin
of products for lower sample rate, low power applications.
