Texas Instruments  INA271AIDR

The INA270 andINA271 family of voltage-output, current-sense amplifiers can sense drops across shunt resistors atcommon-mode voltages from –16 V to +80 V, independent of the supply voltage. The INA270 and INA271pinouts readily enable filtering.

The INA270 and INA271 are available with two gain options: 14 V/V and 20 V/V. The 130-kHzbandwidth simplifies use in current-control loops.

The INA270 and INA271 operate from a single +2.7-V to +18-V supply, drawing 700 µA(typical) of supply current. The devices are specified over the extended operating temperaturerange of –40°C to +125°C and are offered in an SOIC-8 package.
