说明

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.
