Overview
The AD8212YRMZ, produced by Analog Devices Inc., is a high common-mode voltage current shunt monitor. This device is designed to accurately amplify small differential input voltages in the presence of large common-mode voltages, making it ideal for current monitoring across shunt resistors in various applications. The AD8212YRMZ is particularly useful in controlling loads such as motors and solenoids, and it can operate within a common-mode voltage range of 7 V to 65 V. For higher voltage applications, it can be extended to several hundred volts using an external high voltage breakdown PNP transistor.
