GENERAL DESCRIPTION  
Special circuitry is devoted to output linearity being maintained  
throughout the input differential voltage range of 0 mV to 2ꢀ0 mV,  
regardless of the common-mode voltage present. The AD8213  
also features additional pins that allow the user to low-pass filter  
the input signal before amplifying, via an external capacitor to  
ground. The AD8213 has an operating temperature range of  
−40ºC to +12ꢀºC and is offered in a small 10-lead MSOP package.  
The AD8213 is a dual-channel, precision current sense amplifier. It  
features a set gain of 20 V/V, with a maximum 0.ꢀ5 gain error  
over the entire temperature range. The buffered output voltage  
directly interfaces with any typical converter. Excellent common-  
mode rejection from −2 V to +6ꢀ V, is independent of the ꢀ V  
supply. The AD8213 performs unidirectional current measure-  
ments across a shunt resistor in a variety of industrial and  
automotive applications, such as motor control, solenoid  
control, or battery management.
