Overview
The AD9788BSVZRL is a high-performance, 16-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD9785/AD9787/AD9788 family, which are designed for high dynamic range transmit applications. The AD9788BSVZRL offers a sample rate of 800 MSPS, making it suitable for multicarrier generation up to the Nyquist frequency. It features a low power 32-bit complex NCO, which allows for carrier placement anywhere in the DAC bandwidth while minimizing additional power consumption.
