Texas Instruments INA241EVM, User Manual, Page: 5 / 18

3 Hardware
The INA241EVM provides a basic functional evaluation of the INA241x. 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 INA241EVM is
one PCB with five optional PCB cutouts the engineer can use to test each of the five gain options (1 to 5) listed
in
Table 2-1 . Each PCB cutout has one INA241 n device (where n is 1, 2, 3, 4, or 5), test points and sockets for
external hardware connections, and pads to solder down optional circuitry. Only gain options A1, A2, and A3 are
populated.
3.1 Features
The INA241EVM 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
• Multiple input signal options, including a method to solder a shunt resistor (2512) and safely measure current
up to 10 A.
See the device data sheets for comprehensive information about the INA241EVM and the available gain options.
