  • Page 5: Hardware

    The TMCS1101 is an isolated, current-sense op amp that provides ease-of-use and high performance. The TMCS1101EVM is intended to provide basic functional evaluation of all TMCS1101 gain variants. The TMCS1101EVM is not laid out for electromagnetic compatibility (EMC) testing. The TMCS1101EVM consists of one PCB that can be snapped apart into eight individual segments;...

  • Page 6: Circuitry

    U1xy is the TMCS1101 isolated current-sense amplifier. Eight segments are supplied within the TMCS1101EVM board. Each segment is populated with one of the available device gains for bidirectional or unidirectional sensing. This configuration enables users to test the devices and determine the best gain setting for a given application.
