Description

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.
