The INA181 is a family of cost-optimized,
bidirectional, current-sense amplifiers (also called
current-shunt monitors) that sense voltage drops
across current-sense resistors at common-mode
voltages from –0.2 V to +26 V, independent of the
supply voltage. The INA181 integrates a matched
resistor gain network in four, fixed-gain device
options: 20 V/V, 50 V/V, 100 V/V, or 200 V/V. This
matched gain resistor network minimizes gain error
and reduces the temperature drift.
The INA181 operates from a single 2.7-V to 5.5-V
power supply, drawing a maximum of 260 μA of
supply current.
All device options are specified over the extended
operating temperature range of –40°C to +125°C, and
are available in a 6-pin, SOT-23 package. INA181A1IDBVR
