Overview
The AD9164BBCZ, produced by Analog Devices Inc., is a high-performance 16-bit digital-to-analog converter (DAC) and direct digital synthesizer (DDS). This component supports update rates up to 6 GSPS and is designed for the most demanding high-speed radio frequency (RF) DAC applications. The DAC core utilizes a quad-switch architecture combined with a 2× interpolator filter, enabling an effective DAC update rate of up to 12 GSPS in certain modes. The device also features a bank of 32, 32-bit numerically controlled oscillators (NCOs) for advanced signal synthesis capabilities.
