Overview
The AD9102BCPZ from Analog Devices Inc. is a high-performance digital-to-analog converter (DAC) and waveform generator. It integrates on-chip pattern memory for complex waveform generation along with a direct digital synthesizer (DDS). The DDS is a 14-bit output, capable of up to 180 MSPS master clock sine wave generation, with a 24-bit tuning word that allows for 10.8 Hz/LSB frequency resolution. This device is designed for applications requiring precise and flexible waveform generation, including medical instrumentation, portable instrumentation, signal generators, arbitrary waveform generators, and automotive radar.
