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 maximum conversion rate exceeding 600 MSPS.
Manufactured on a CMOS process, the AD9725 uses a proprietary switching technique that enhances dynamic performance.
The current output of the AD9725 can be easily configured for various single-ended or differential circuit topologies.
