Description

The INA270 and INA271 family of current-shunt monitors with voltage output can sense drops across current shunts at common-mode voltages from -16V to +80V, independent of the supply voltage. The INA270 and INA271 pinouts readily enable filtering.

The INA270 and INA271 are available with two output voltage scales: 14V/V and 20V/V. The 130kHz bandwidth simplifies use in current-control loops.

The INA270 and INA271 operate from a single +2.7V to +18V supply, drawing a maximum of 900µA of supply current. They are specified over the extended operating temperature range of -40°C to +125°C and are offered in an SO-8 package.
