**The AD7472BRUZ: A 1 MSPS, 12-Bit SAR ADC in a Tiny TSSOP Package**

In the world of data acquisition, the constant demand is for higher speed, greater accuracy, and smaller size. The **AD7472BRUZ from Analog Devices** stands as a testament to this engineering pursuit, successfully integrating high performance into a remarkably compact form factor. This 12-bit, successive approximation register (SAR) analog-to-digital converter (ADC) is a powerful solution for a wide array of space-constrained and power-sensitive applications.

At the heart of the AD7472BRUZ is a **high-speed SAR architecture capable of 1 million samples per second (1 MSPS)**. This sampling rate makes it suitable for capturing dynamic signals in applications such as portable instrumentation, medical imaging, optical networking, and high-speed data acquisition systems. The ADC provides true 12-bit resolution, ensuring excellent linearity and low noise for precise digital representation of analog signals.

A defining feature of this component is its **miniscule 16-lead TSSOP package**. This incredibly small footprint is a critical advantage for modern PCB designs where board real estate is at a premium. Despite its size, the AD7472BRUZ does not compromise on functionality or ease of use. It operates from a single 2.35 V to 5.25 V power supply, making it compatible with both 3 V and 5 V system logic. Furthermore, it features **exceptionally low power consumption**, drawing just 11 mW at 1 MSPS with a 5 V supply and scaling down significantly with reduced throughput, a key benefit for battery-operated devices.

The interface is a simple, SPI-compatible 3-wire serial bus, which allows for easy connection to modern microcontrollers, DSPs, and FPGAs. This streamlined digital interface reduces the number of necessary I/O pins and simplifies the overall system design. The combination of high speed, low power, and a simple serial interface makes the AD7472 an exceptionally versatile ADC.

**ICGOODFIND:** The AD7472BRUZ is a stellar example of analog integration, delivering **high-performance 12-bit conversion at 1 MSPS** in an ultra-compact TSSOP package. Its **low power operation and simple serial interface** make it an ideal choice for designers tackling the challenges of portable, compact, and efficient electronic systems.
