INA282AIDR Description

INA282AIDR is a voltage output current shunt monitor 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. The current sense amplifier operates from a single +2.7-V to +18-V supply, drawing a maximum of 900 μA of supply current. The INA282AIDR is specified over the extended operating temperature range of –40°C to +125°C and offered in SOIC-8 packages.
