The INA2191EVM provides a basic functional evaluation of the INA2191. 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 INA2191EVM 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 Table 1-1. Each PCB cutout has one INA2191An 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.
