3 Description

The INA180, INA2180, and INA4180 (INAx180)

current sense amplifiers are designed for costoptimized

applications. These devices are part of a

family of current-sense amplifiers (also called currentshunt

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 INAx180 integrate 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.

All these devices operate from a single 2.7-V to 5.5-V

power supply. The single-channel INA180 draws a

maximum supply current of 260 μA; whereas, the

dual-channel INA2180 draws a maximum supply

current of 500 μA, and the quad channel draws a

maximum supply current of 900 μA.

The INA180 is available in a 5-pin, SOT-23 package

with two different pin configurations. The INA2180 is

available in an 8-pin, VSSOP package. The INA4180

is available in a 14-pin, TSSOP package. All device

options are specified over the extended operating

temperature range of –40°C to +125°C.
