DESCRIPTION
The INA282 family, which includes the INA282,
INA283, INA284, INA285, and INA286 devices, are
voltage output current shunt monitors 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.
These current shunt monitors operate from a single
+2.7V to +18V supply, drawing a maximum of 900μA
of supply current. They are specified over the
extended operating temperature range of –40°C to
+125°C, and offered in an SOIC-8 package.
