Overview of INA271AIDR
The INA270 and INA271 family of voltage-output, current-sense amplifiers can sense drops across shunt resistors 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 gain options: 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 700 µA (typical) of supply current. The devices are specified over the extended operating temperature range of –40°C to +125°C and are offered in an SOIC-8 package.
