**AD5324BRMZ-REEL: A 12-Bit Quad Voltage Output DAC with I²C Interface and On-Chip Reference**
In the realm of digital-to-analog conversion, the integration of multiple channels, precision, and system-level features into a single package is a critical driver for modern design efficiency. The **AD5324BRMZ-REEL** from Analog Devices stands out as a premier solution, **combining a 12-bit quad voltage output DAC, an I²C interface, and a precision on-chip reference** in a compact MSOP-10 package. This integration makes it an exceptionally powerful component for a wide array of applications, from industrial instrumentation to automated test equipment and beyond.
The core of the AD5324 is its four 12-bit digital-to-analog converters. Each DAC is equipped with its own input register and a DAC register, allowing for **simultaneous updates of all outputs** via a software command. This feature is invaluable in multi-axis control systems where coordinated output changes are paramount. The voltage outputs provide a range of 0 V to VREF, ensuring flexibility in setting the analog output span.

A significant advantage of this DAC is its **on-chip 2.5 V reference**, which has an initial accuracy of ±10 mV. The inclusion of this reference simplifies system design dramatically by eliminating the need for an external reference IC, thereby saving board space, reducing the bill of materials (BOM) cost, and enhancing overall system reliability. Designers also have the option to disable the internal reference and apply an external one, offering greater flexibility for applications demanding a different voltage range or higher precision.
Communication is handled through a versatile **I²C-compatible serial interface**, which supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes. This two-wire interface minimizes the number of GPIOs required from the controlling microcontroller or processor, making it ideal for space-constrained and complex systems. The interface also allows for addressing multiple devices on the same bus, enabling the control of a large number of analog outputs with minimal wiring.
The device is designed for robust performance, operating from a single **2.5 V to 5.5 V supply**. Its low power consumption is a key attribute, drawing just 4 µA in power-down mode and 0.4 mA during normal operation at 3 V, which is crucial for battery-powered and portable applications. The AD5324BRMZ-REEL is offered in a reel packaging, making it optimized for high-volume automated manufacturing.
**ICGOO FIND**: The AD5324BRMZ-REEL is a highly integrated and efficient solution for system designers seeking to add multiple channels of precision analog output. Its combination of a quad 12-bit DAC, internal reference, and space-saving I²C interface provides an exceptional blend of performance, simplicity, and value, streamlining design and accelerating time-to-market for a diverse set of applications.
