**AD8210WYRZ-R7: A High Common-Mode Voltage, Current-Shunt Monitor**

In the realm of precision electronics, accurately measuring current in systems with high voltages is a persistent challenge. The **AD8210WYRZ-R7** from Analog Devices stands out as a specialized solution, engineered to excel as a **high common-mode voltage, current-shunt monitor**. This device is critical for applications requiring precise current sensing in the presence of rapidly shifting or elevated voltages, such as in industrial motor controls, automotive systems, and power management.

The core function of the AD8210 is to amplify a small voltage developed across a current-sensing shunt resistor. What sets it apart is its remarkable ability to reject and operate accurately with a common-mode voltage—the voltage at which the shunt resistor "floats"—ranging from **-2 V to +65 V**. This extensive range is a key performance differentiator, allowing it to function reliably in harsh electrical environments where other amplifiers would fail. Furthermore, it features a fixed gain of **20 V/V**, providing a large, buffered output voltage that is easy for downstream analog-to-digital converters (ADCs) or microcontrollers to process.

A significant advantage of this monitor is its **integrated architecture**. By combining a pre-amplifier and a precision trimmed thin-film gain network on a single chip, the AD8210 achieves excellent performance characteristics. It offers a **low initial gain error of just ±0.3% (max)** and an outstanding common-mode rejection ratio (CMRR) of **80 dB (min)**, ensuring that the amplified signal reflects the actual current with minimal interference from the high common-mode voltage. Its wide bandwidth of **450 kHz** also makes it suitable for monitoring dynamic current waveforms in switching applications.

Housed in a compact **SOIC-8 package**, the AD8210WYRZ-R7 is designed for space-constrained applications. Its -R7 suffix denotes a tape-and-reel packaging format, making it ideal for automated high-volume assembly lines. The device operates over the industrial temperature range of **-40°C to +125°C**, guaranteeing robust performance in virtually any operating condition.

**ICGOODFIND**: The AD8210WYRZ-R7 is an exceptional current-shunt monitor that delivers **high accuracy, robustness, and simplicity** for high-side current sensing. Its ability to perform with precision in high-voltage environments makes it an indispensable component for designers building reliable and efficient power and control systems.
