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.
