GENERAL DESCRIPTION

The AD8214 is a fast response, high common-mode voltage, current shunt comparator . The device operates on the high side rail of any DC current sensing application, provided the voltage is between 5 V and 65 V . Internally , the AD8214 features a fast comparator that is optimized for high side operation. An internal Zener regulator powers the circuit with respect to the high side DC rail. In addition, user access to this 2.4V regulator , allows for setting a comparator threshold voltage via external resistors.
