Overview
The AD9859YSVZ, produced by Analog Devices Inc., is a high-performance Direct Digital Synthesizer (DDS) that integrates advanced DDS technology with a high-speed, high-performance 10-bit Digital-to-Analog Converter (DAC). This component is designed to generate frequency-agile analog output sinusoidal waveforms up to 200 MHz, making it ideal for applications requiring fast frequency hopping and fine tuning resolution. The AD9859 operates over an extended industrial temperature range of –40°C to +105°C and is packaged in a 48-lead TQFP/EP package.
