INA28x-Q1 Automotive Grade, –14-V to +80-V, Bidirectional, High Accuracy,  
Low- or High-Side, Voltage Output, Current Shunt Monitor  
1 Features  
3 Description  
The INA28x-Q1 family includes the INA282-Q1,  
INA283-Q1, INA284-Q1, INA285-Q1, and INA286-Q1  
devices. These devices are voltage output current  
shunt monitors that can sense drops across shunts at  
common-mode voltages from –14 V to +80 V,  
independent of the supply voltage. The low offset of  
the zero-drift architecture enables current sensing  
with maximum drops across the shunt as low as 10  
mV full-scale.
