DESCRIPTION
The INA271 is a current-shunt monitor with voltage
output and can sense drops across current shunts at common-mode voltages from –16V to +80V,
independent of the supply voltage. The INA271
pinouts readily enable filtering.
The INA271 is available with a 20V/V output voltage
scale. The 130kHz bandwidth simplifies use in
current-control loops.
The INA271 operates from a single +2.7V to +18V
supply, drawing a maximum of 1600μA of supply
current. This device is specified over the extended
operating temperature range of –55°C to +210°C.
