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.
