The AD9835 is a 50MHz direct digital synthesizer with waveform generator functionality. The AD9835 features a 5V power supply, 50MHz speed, integrated COS lookup table, integrated 10-bit DAC, serial loading, power-down option, temperature range of -40°C to +85°C, 200mW power consumption, and a 16-Lead TSSOP package.
The AD9835 is a 90 MHz Direct Digital Synthesizer (DDS) from Analog Devices that integrates a phase accumulator, COS lookup table, and a 10‑bit DAC on a single CMOS chip. It offers serial loading, power‑down mode, and a wide temperature range for low‑power RF and communication applications.
The document includes detailed specifications such as 10‑bit resolution, 50 MSPS update rate, and full‑scale current output, as well as pin configuration, timing diagrams, absolute maximum ratings, and ordering information for the 16‑lead TSSOP package.
