Overview
The AD9739BBCZ, produced by Analog Devices Inc., is a high-performance 14-bit, 2.5 GSPS RF digital-to-analog converter (DAC). This component is designed to synthesize wideband signals from DC up to 3.0 GHz, making it suitable for various high-frequency applications. The AD9739 features a proprietary quad-switch DAC architecture, which provides exceptional AC linearity performance and enables mix mode operation. It operates on 1.8 V and 3.3 V supplies and is packaged in a 160-ball chip scale ball grid array (CSPBGA) to minimize package parasitics.
