5.1 Schematics

Figure 5-1 shows the schematic of the A1 sub board on the TMCS1100EVM PCB. Only the schematic for the A1 (50 mV/A) gain variant is included as all variants use the same circuit and same PCB layout. All components associated with the 50-mV/A TMCS1100 A1 gain variant have the letter A appended at the end. The 100-mV/A A2 gain variant has B appended, the 200-mV/A A3 gain variant has C appended, and the 400-mV/A A4 gain variant has a D appended.
