2.2 INA183EVM

The INA183EVM is intended to provide basic functional evaluation of this device family. The fixture layout is not intended to be a model for the target circuit, nor is it laid out for electromagnetic compatibility (EMC) testing.

The layout of the INA183EVM printed-circuit board (PCB) is designed to provide the following features:

  • Easy handling of the small package
  • Easy access to all device pins
  • Space for optional input filtering capacitors and resistors
  • Space for surface mount shunt resistors
  • Evaluation of all gain options through provided device boards

The INA183EVM allows the user to install a shunt resistor, and then connect both the common-mode voltage and load to develop the input voltage, or omit the shunt resistor and apply a differential voltage directly to the device input. This flexibility allows a user to test the device operation in a simulated manner as well as an actual application.
