SBOS554B –MARCH 2012–REVISED DECEMBER 2015
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.
