The INA180 is an Op-Amp current sense integration circuit that provides ease of use and high performancce. The INA181 has the same capabilities of the INA180 but with the addition of the reference pin that enables bidirectional current measurements. The INA180-181EVM is intended to provide 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 INA180-181EVM consists of one PCB with an option to cut out eight individual PCBs one for each of the eight devices (INA180A1, INA180A2, INA180A3, INA180A4, INA181A1, INA181A2, INA181A3 and INA181A4).
