INA2180-2181 Evaluation Module User's Guide

Overview
The INA2180 family of current-shunt monitors (also called current-sense amplifiers) can sense drops
across shunts at common-mode voltages from –0.2 V to +26 V, independent of the supply voltage. Four
fixed gains are available: 20 V/V, 50 V/V, 100 V/V, and 200 V/V. The INA2181 family has the same
capabilities as the INA2180 family but with the addition of the reference pin that enables bidirectional
current measurements. These devices operate from a single 2.7-V to 5.5-V power supply, drawing a
maximum of 260
μ
A of supply current per amplifier channel.
The INA2180 devices are currently available in a VSSOP(8) and the INA2181 devices are available in a
TSSOP(14) surface-mount packages.

INA2180-2181EVM Hardware
The INA2180 is a current sense integration solution that provides ease of use and high performance. The
INA2181 has the same capabilities as the INA2180 but with the addition of the reference pin that enables
bidirectional current measurements. The INA2180-2181EVM provides basic functional evaluation of this
device family. The fixture layout is not intended to be a model for the target circuit, nor is it laid out for
electromagnetic compatibility (EMC) testing. The INA2180-2181EVM consists of one PCB with an option
to cut out eight individual PCBs - one for each of the eight devices (INA2180A1, INA2180A2, INA2180A3,
INA2180A4, INA2181A1, INA2181A2, INA2181A3 and INA2181A4).
