Overview
The AD9952YSV, produced by Analog Devices Inc., is a high-performance direct digital synthesizer (DDS) that integrates advanced DDS technology with a 14-bit digital-to-analog converter (DAC). This component is designed to generate frequency-agile analog output sinusoidal waveforms up to 200 MHz, making it suitable for applications requiring fast frequency hopping and fine tuning resolution. The AD9952 operates over an extended industrial temperature range of –40°C to +105°C and is packaged in a 48-lead Thin Plastic Quad Flat Package (TQFP/EP) with an exposed pad for ground connection.
