3 Description
The INA180 is a family of cost-optimized, 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
INA180 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 INA180 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 5-pin, SOT-23 package with two
different pin configurations.
