The TMCS1100 is an isolated, current-sense op amp that provides ease-of-use and high performance. The TMCS1100EVM is intended to provide basic functional evaluation of all TMCS1100 gain variants. The TMCS1100EVM is not laid out for electromagnetic compatibility (EMC) testing. The TMCS1100EVM consists of one PCB that can be snapped apart into four individual segments; one for each of the four gain variants:

  • TMCS1100A1
  • TMCS1100A2
  • TMCS1100A3
  • TMCS1100A4
