DESCRIPTION/ORDERING INFORMATION

The INA270 and INA271 family of current-shunt monitors with voltage output can sense voltage drops across

current shunts at common-mode voltages from –16 V to 80 V, independent of the supply voltage. The INA270

and INA271 pinouts readily enable filtering.

The INA270 and INA271 are available with two output voltage scales: 14 V/V and 20 V/V. The 130-kHz

bandwidth simplifies use in current-control loops.

The INA270 and INA271 operate from a single 2.7-V to 18-V supply, drawing a maximum of 900 mA 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.
