**AD8217BRMZ-RL: A High Common-Mode Voltage, Current-Shunt Monitor**

In modern electronic systems, accurately measuring current is critical for applications ranging from motor control and power management to battery monitoring and industrial automation. The **AD8217BRMZ-RL** from Analog Devices stands out as a specialized current-shunt monitor designed to deliver precision and reliability in environments with high common-mode voltages.

This device is engineered to **amplify a small differential voltage** generated across a shunt resistor in the presence of high common-mode voltages up to **65 V**, independent of the supply voltage. Its ability to reject high common-mode noise while accurately extracting the differential signal makes it particularly valuable in noisy industrial or automotive settings. The AD8217 offers a fixed gain of 20 V/V, providing a large output voltage swing that simplifies interfacing with analog-to-digital converters (ADCs) or other monitoring circuitry.

A key feature of the AD8217 is its **wide operating supply voltage range from 3 V to 5.5 V**, making it suitable for both 3.3 V and 5 V systems. It also boasts a **low quiescent current of 550 µA**, which is crucial for power-sensitive applications. The device operates over an extended temperature range (-40°C to +125°C), ensuring performance stability in harsh conditions.

The AD8217BRMZ-RL comes in a compact MSOP-8 package, ideal for space-constrained PCB designs. Its integrated design minimizes external component requirements, reducing both board space and overall system cost. Typical applications include high-side current sensing in DC motors, solenoid controls, power supply units, and battery management systems.
