AD9852 is a CMOS 300 MHz Complete-DDS produced by Analog Devices. It has a 300 MHz internal clock rate, integrated 12-bit output DACs, ultra-wide bandwidth, and low power consumption.
The AD9852 digital synthesizer combines a high‑speed DDS core with dual 12‑bit DACs and a comparator to deliver agile frequency, phase and amplitude control. It supports internal or external reference clocks up to 300 MHz and offers multiple programming interfaces (SPI, parallel, 2‑wire, 3‑wire).
The device is supplied in an 80‑lead LQFP package, operates from a single 3.3 V supply, and includes ESD protection. Detailed specifications, pin functions, and mechanical drawings are provided for designers of RF, radar, test‑and‑measurement and communication systems.

The AD9852 can operate with an internal clock up to 300 MHz.
The device runs from a single 3.3 V supply.
Both DACs have a 12‑bit resolution.
It is offered in a thermally‑enhanced 80‑lead LQFP (AD9852ASQ) and a standard 80‑lead LQFP (AD9852AST).
