The INA4290EVM provides a basic functional evaluation of the INA4290. 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 INA4290EVM is one PCB with five optional PCB cutouts the engineer can use to test each of the five gain options (1 to 5) listed in INA4290 Gain Option Summary. Each PCB cutout has one INA4290An device (where n is 1, 2, 3, 4, or 5), test points and sockets for external hardware connections, and pads to solder down optional circuitry.
