**AD5691RBRMZ: A 16-Bit nanoDAC+ with I2C Interface and On-Chip Reference**
In the realm of precision analog signal generation, the integration of high performance, compact form factor, and system simplicity is paramount. The **AD5691RBRMZ from Analog Devices** stands out as a pivotal solution, encapsulating these features into a single, robust component. This device is a **16-bit, voltage-output digital-to-analog converter (DAC)** that belongs to the innovative **nanoDAC+® product family**, renowned for its combination of miniaturization and high accuracy.
A defining characteristic of the AD5691RBRMZ is its **integrated, high-precision on-chip 2.5 V reference**. This feature is critical as it eliminates the need for an external reference component, which not only saves valuable board space but also reduces the overall bill of materials (BOM) and simplifies the design process. The internal reference offers exceptional stability, with a typical drift of just **5 ppm/°C**, ensuring consistent and reliable performance across varying temperature conditions.
Communication with the device is efficiently handled via a **2-wire I2C-compatible serial interface**, supporting standard (100 kbps), fast (400 kbps), and high-speed (3.4 Mbps) modes. This ubiquitous interface allows for easy connection to a vast array of microcontrollers and processors, facilitating straightforward integration into complex digital systems. The interface also features a programmable address, enabling up to **two devices** to share the same bus, which enhances design flexibility in multi-channel applications.
Despite its tiny 2 mm × 2 mm WLCSP package, the AD5691RBRMZ delivers impressive performance. It exhibits **excellent DC performance** with ±1 LSB (max) INL and DNL error, ensuring highly linear voltage output. The device operates from a single **2.7 V to 5.5 V supply**, making it suitable for a wide range of applications, from portable battery-powered equipment to industrial automation systems. Its low power consumption is another key benefit, drawing just 0.15 mA at 3 V, which is crucial for power-sensitive designs.
The application spectrum for this nanoDAC+ is broad, including **portable instrumentation, digital gain and offset adjustment, programmable voltage and current sources, and industrial process control**. Its ability to provide a precise, stable analog output from a digital command makes it indispensable in closed-loop systems and for setting critical bias points.
**ICGOOODFIND**: The AD5691RBRMZ is a superior choice for designers seeking a compact, fully integrated, and high-accuracy 16-bit DAC. Its **on-chip reference, I2C interface, and miniature package** offer a complete, space-efficient solution that simplifies design, reduces costs, and accelerates time-to-market for a multitude of precision applications.
