3 Description
The INA28x-Q1 family includes the INA282-Q1,
INA283-Q1, INA284-Q1, INA285-Q1, and INA286-Q1
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.
