**AD9762ARUZ: A 12-Bit, 125 MSPS High-Speed TxDAC+ Digital-to-Analog Converter**

In the realm of high-speed data conversion, the **AD9762ARUZ** stands out as a pivotal component for applications demanding precision and speed. As a member of Analog Devices' esteemed **TxDAC+® product family**, this 12-bit digital-to-analog converter (DAC) is engineered to deliver exceptional performance at sampling rates up to **125 MSPS (Mega Samples Per Second)**. It is specifically designed to meet the rigorous requirements of communication systems, medical imaging, and high-definition video processing.

The core architecture of the AD9762ARUZ leverages a segmented current-steering structure, which minimizes glitch energy and enhances dynamic performance. This design ensures **outstanding spurious-free dynamic range (SFDR)** and low harmonic distortion, critical for maintaining signal integrity in broadband applications. The DAC incorporates a proprietary double-buffered input latch, allowing for easy interface with high-speed digital signal processors (DSPs) and field-programmable gate arrays (FPGAs). Its **differential current outputs** provide flexibility, enabling users to configure the output for optimal common-mode rejection and noise immunity.

Power efficiency is another hallmark of the AD9762ARUZ. Operating from a single +3.3V or +5V supply, it consumes just 175 mW at 125 MSPS with a +3.3V supply, making it suitable for power-sensitive designs. The device also features a sleep mode, reducing power consumption to under 25 mW when not in active use. Additionally, its internal reference circuit ensures consistent performance across varying environmental conditions, eliminating the need for external references and simplifying board layout.

The integration of the AD9762ARUZ into systems is streamlined by its 28-lead TSSOP package, which offers a compact footprint without compromising thermal performance. Its robust design supports **direct synthesis of waveforms** up to the Nyquist frequency, making it ideal for quadrature modulation, waveform generation, and direct digital synthesis (DDS) applications.

ICGOODFIND: The AD9762ARUZ exemplifies high-speed DAC innovation, combining **low power consumption**, **excellent dynamic performance**, and **ease of integration** to address the challenges of modern digital-to-analog conversion.
