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.
