TMCS1100EVM

3

Hardware

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

3.1

Features

The layout of the TMCS1100EVM PCB is designed to provide the following features:

•

Evaluation of all gain variants for the TMCS1100

•

Ease-of-access to device pins with test points

•

Evaluation of high-side and low-side configurations

•

Buffered reference with a user-defined voltage divider

•

On-board temperature sensor

See the

data sheet for comprehensive information about the TMCS1100.
