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.
