**AD5664RBRMZ-3: A 16-Bit NanoDAC+ with I2C Interface for Precision Analog Output**

In the realm of precision analog signal generation, the **AD5664RBRMZ-3** from Analog Devices stands out as a premier solution for applications demanding high accuracy, compact size, and simple digital control. This device is a member of the renowned **NanoDAC+** family, integrating a complete 16-bit digital-to-analog converter (DAC), a precision internal reference, and an I2C interface into a single, tiny package.

The core of the AD5664RBRMZ-3 is its **16-bit voltage-output DAC**, which delivers exceptional performance with **low noise and high accuracy**. A significant feature is its integrated **2.5 V, 5 ppm/°C internal reference**, which is enabled by default upon power-up. This eliminates the need for an external reference component, saving valuable board space and simplifying design complexity while ensuring stable performance over temperature variations. The DAC offers a flexible output range, configurable via software to either a **0 V to Vref** or **0 V to 2*Vref** span, providing design versatility for different system requirements.

Communication is handled through a versatile **I2C-compatible serial interface**, supporting standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes. This two-wire interface allows for easy connection to a vast array of microcontrollers and processors, minimizing the number of GPIO pins required. The interface also includes an optional CRC error-checking feature for enhanced communication reliability in electrically noisy environments.

Housed in a compact **10-lead MSOP package**, the device is designed for space-constrained applications. Its **low power consumption** is a key attribute, making it suitable for portable and battery-powered equipment. Furthermore, the AD5664RBRMZ-3 includes a per-channel power-down mode, where the DAC output can be switched to a known high-resistance state, reducing the typical current consumption to under 1 µA.

The combination of high resolution, a built-in reference, and a small form factor makes the AD5664RBRMZ-3 ideal for a wide range of applications, including **process control, data acquisition systems, digital gain and offset adjustment, and programmable voltage sources**.

**ICGOOODFIND**: The AD5664RBRMZ-3 is a highly integrated, precision 16-bit DAC that delivers outstanding performance and design flexibility. Its combination of a built-in reference, I2C interface, and miniature package makes it an superior choice for engineers seeking to add high-accuracy analog outputs to their designs efficiently.
