3 Description
The INA28x family includes the INA282, INA283,
INA284, INA285, and INA286 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.
These current sense amplifiers operate from a single
+2.7-V to +18-V supply, drawing a maximum of 900
μA of supply current. These devices are specified
over the extended operating temperature range of
–40°C to +125°C, and offered in SOIC-8 and
VSSOP-8 packages.
