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 –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 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 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.
