INA191EVM
2 Hardware
The INA191EVM is intended to provide basic functional evaluation of the INA191. 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 INA191EVM consists of one PCB with an option to cut out five individual PCBs, one for each
of the five gain options (A1 to A5) listed in
Table 1 . Each of the PCB cutouts consists of one INA191Ax
device (where x is 1, 2, 3, 4, or 5), and test points and sockets for external hardware connections, as well
as pads to solder down optional circuitry.
2.1 Features
The INA191EVM PCB provides the following features:
• Evaluation of all gain options through provided device boards
• Ease of access to device pins with test points
• Pads and sockets for optional filtering at the input pins and output pin
• Pads for optional input protections devices (TVS or Zener diodes)
• Multiple input signal options, including a method to solder the shunt resistor (0603, 0805, 1206) and
safely measure current up to 15 A.
See the device data sheet listed in Table 3 for comprehensive information about the INA191 and the
available gain options.
