**AD7495BR: A 16-Channel, 12-Bit SAR ADC for High-Speed, Low-Power Data Acquisition Systems**

In the realm of data acquisition, the ability to accurately and efficiently digitize multiple analog signals is paramount across a wide array of applications, from industrial process control and medical instrumentation to automated test equipment. The **AD7495BR from Analog Devices** stands out as a highly integrated solution, engineered to meet the demanding requirements of modern multi-channel systems. This 16-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) combines high-speed performance with remarkably low power consumption, establishing itself as a cornerstone component for designers.

At the core of the AD7495BR's functionality is its **16-channel multiplexer**, which can be configured for either 16 single-ended or 8 pseudo-differential inputs. This exceptional channel density drastically reduces the component count on a board, simplifying system design and saving valuable space. A dedicated address register allows for flexible channel sequencing, enabling users to program the order in which channels are converted, which is invaluable for prioritizing critical signals.

The ADC leverages a robust **SAR architecture**, renowned for its precision and deterministic behavior. It delivers true 12-bit resolution without any missing codes, ensuring high accuracy for sensitive measurements. With a **fast throughput rate of up to 1 MSPS** (mega samples per second), the AD7495BR is capable of capturing rapidly changing signals, making it suitable for dynamic monitoring and control applications. Despite this high speed, it operates with **exceptionally low power dissipation**, typically consuming just 9.5 mW at 1 MSPS with a 5 V supply. This feature is critical for portable, battery-operated, or other power-sensitive devices.

Ease of integration is another key strength. The device features a standard **high-speed serial interface (SPI/QSPI™/MICROWIRE™/DSP compatible)** that simplifies connections to modern microcontrollers and digital signal processors (DSPs). The serial interface also minimizes the number of digital lines required, reducing noise and crosstalk on the board. An internal oscillator eliminates the need for an external clock source, further simplifying the design process. The AD7495BR is offered in a compact 48-lead LQFP package, optimized for space-constrained applications.
