GENERAL DESCRIPTION
The AD9119/AD9129 are high performance, 11-/14-bit RF digital to-analog converters (DACs) supporting data rates up to 2.8 GSPS. The DAC core is based on a quad-switch architecture that enables dual-edge clocking operation, effectively increasing the DAC update rate to 5.6 GSPS when configured for Mix-Mode™ or 2× interpolation. The high dynamic range and bandwidth enable multicarrier generation up to 4.2 GHz.
