FEATURES  
DESCRIPTION  
The INA282-Q1 is a voltage output current shunt  
monitor that can sense drops across shunts at  
common-mode voltages from –14V to +80V,  
independent of the supply voltage. The low offset of  
the Zerø-Drift architecture enables current sensing  
with maximum drops across the shunt as low as  
10mV full-scale.

This current shunt monitor operates from a single  
+2.7V to +18V supply, drawing a maximum of 900μA  
of supply current. It is specified over the extended  
operating temperature range of –40°C to +125°C, and  
offered in an SOIC-8 package.
