Overview
The AD9119BBCZ, produced by Analog Devices Inc., is a high-performance 11-bit RF digital-to-analog converter (DAC). This component is part of the AD9119/AD9129 family, which supports data rates up to 2.85 GSPS. The DAC core utilizes a quad-switch architecture, enabling dual-edge clocking operation and effectively increasing the DAC update rate to 5.7 GSPS in Mix-Mode™ or 2× interpolation configurations. This architecture enhances the dynamic range and bandwidth, making it suitable for various high-frequency applications, including RF signal synthesis and multicarrier generation up to 4.2 GHz.
