5.1 Schematics

Figure 5-1 and Figure 5-2 show the schematic of the EVM. Figure 5-1 shows the circuitry for the A1 sub board on the INA310AEM. Only the schematic for the A1 version is shown as all variants use the same schematic. The only differences between schematics for different variants and gain versions is that U1 changes to match the device, and the "_1" appended to each component below will change to match the gain number of the device. Figure 5-2 shows the hardware section of the schematic that is not repeated per sub board.
