The AD9725 is a 14-bit digital-to-analog converter (DAC) that
utilizes an LVDS interface to achieve conversion rates in excess
of 600 MSPS. It is in a family of pin compatible converters that
offers selection of 10-bit, 12-bit, 14-bit, and 16-bit resolution
grades. All of the devices share the same interface options, small
outline package, and pinout, providing an upward or downward
component selection path based on performance, resolution
and cost.
PRODUCT HIGHLIGHTS
Ultralow noise and intermodulation distortion (IMD) enable
high quality waveform synthesis at intermediate frequencies up
to 200 MHz.
LVDS receivers support SDR or DDR modes, with the maxi-
mum conversion rate exceeding 600 MSPS.
Manufactured on a CMOS process, the AD9725 uses a proprie-
tary switching technique that enhances dynamic performance.
The current output of the AD9725 can be easily configured for
various single-ended or differential circuit topologies.
