AD9129 - Analog Devices

AD9129 RF Digital-to-Analog Converter

The AD9119/AD9129 are high performance, 11-/14-bit RF digitalto-analog converters (DACs) supporting data rates up to 2.85 GSPS. The DAC core is based on a quad-switch architecture that enables dual-edge clocking operation, effectively increasing the DAC update rate to 5.7 GSPS when configured for Mix-Mode™ or 2× interpolation. The high dynamic range and band.
