GENERAL DESCRIPTION  
The AD8214 is a fast, high common-mode voltage threshold  
detector, which operates with a single supply of 5 V to 65 V.  
Internally the AD8214 features a fast comparator that is  
optimized for high side operation. It also includes a stable  
2.4 V series regulator, which is referenced with respect to the  
supply voltage. The purpose of the regulator is to provide  
power to the internal electronics, and set an input comparison  
threshold below the supply voltage. The inputs of the AD8214  
may be operated at, slightly above, or below the power supply.  
The differential voltage range between the inputs of the  
AD8214 is 500 mV.  
voltages are referenced to the supply voltage, as is the  
internal 2.4 V regulator. The input-to-output response time  
is typically <100 ns.  
As the output switches from low to high, a small hysteresis  
(10 mV) is activated to minimize the effects of noise in the  
system, and prevent any false state conditions.  
The AD8214 is available in an 8-lead MSOP package. The  
operating temperature range is –40°C to +125°C, making it  
ideal for industrial, consumer, and automotive applications.  
The device features a current output. This current is <100 nA  
when –IN > +IN and 1 mA when +IN > –IN. The input
