Overview
The AD9951YSVZ, produced by Analog Devices Inc., is a direct digital synthesizer (DDS) that integrates advanced DDS technology with a high-speed, high-performance 14-bit digital-to-analog converter (DAC). This device is capable of generating a frequency-agile analog output sinusoidal waveform up to 200 MHz, making it suitable for applications requiring fast frequency hopping and fine tuning resolution. The AD9951 operates over an extended industrial temperature range of −40°C to +105°C and is housed in a 48-lead TQFP-EP package.
