Schematic, PCB Layout, and Bill of Materials

NOTE:

Board layouts are not to scale. These figures are intended to show how the board is laid out; they are not intended to be used for

manufacturing INA293EVM PCBs.

Schematics

Figure 1

is shown below and is the schematic of the INA293EVM for all gain versions for the A pinout. The difference is noted on the reference

designator ending in the gain option _An.

Figure 2

shows the B1 gain panel and this is also a copy for all the other gain options with the reference

designator ending with the gain option _Bn
