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.INA180A1IDBVR
