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.
