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.
The figures are not intended to be used for manufacturing INA185EVM PCBs.
6.1
Schematic
shows the schematic for the INA185EVM PCB. Only the schematic for the 20-V/V gain variant is
included because all other variants use the same exact circuit with the same layout. All components
associated with the 20-V/V INA185 A1 gain variant have the letter
A
appended at the end. The 50-V/V A2
gain variant has
B
appended, the 100-V/V A3 gain variant has
C
appended, and the 200-V/V A4 gain
variant has a
D
appended.
