**AD7863ARS-2REEL7: A 14-Bit Simultaneous Sampling SAR ADC for High-Performance Industrial Applications**

In the demanding world of industrial automation, motor control, and power conversion, the ability to accurately capture multiple real-world signals at the same precise moment is paramount. The **AD7863ARS-2REEL7** from Analog Devices stands as a pivotal solution, engineered to meet these challenges with its high-performance, simultaneous sampling architecture.

This integrated circuit is a **14-bit, successive approximation register (SAR) analog-to-digital converter (ADC)** that features **four independent ADC cores on a single chip**. This unique design allows it to sample up to four analog input channels simultaneously, eliminating the phase skew that plagues multiplexed ADCs when measuring correlated signals, such as the three-phase currents and voltages in motor drives. The device operates from a single +5 V supply and supports a throughput rate of up to 350 kSPS for each channel, providing both speed and precision.

A key strength of the AD7863ARS-2REEL7 lies in its robust performance tailored for industrial environments. It offers **excellent dynamic performance and fast throughput**, characterized by its low noise and high signal-to-noise ratio (SNR). The ADC integrates sample-and-hold amplifiers, a voltage reference, and all necessary control logic, simplifying system design and reducing the external component count. Its parallel interface ensures fast data transfer to a microcontroller or DSP, which is critical for real-time control loop processing.

Housed in a compact SSOP package, the device is designed for space-constrained applications without compromising on functionality or reliability. Its **simultaneous sampling capability is critical for maintaining data coherence** in complex systems, ensuring that control algorithms receive a true snapshot of system conditions at a specific instant in time. This makes it an indispensable component in applications such as:

* **Multi-axis motor control and drives**

* **Uninterruptible power supplies (UPS) and inverters**

* **Data acquisition systems (DAQ)**

* **Phased-array sonar and instrumentation**

**ICGOOODFIND:** The AD7863ARS-2REEL7 is a highly integrated, system-level solution that delivers **exceptional channel-to-channel matching and phase accuracy**. Its combination of simultaneous sampling, 14-bit resolution, and robust industrial design makes it a superior choice for engineers developing high-performance control and monitoring systems where the integrity of multi-channel data is non-negotiable.
