INA190EVM Hardware
The INA190EVM is intended to provide basic functional evaluation of the INA190 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 INA190EVM consists of one PCB with an option to cut out six individual PCBs, one for
each of the five gain variants (INA190A1, INA190A2, INA190A3, INA190A4, and INA190A5). Each of the
PCB cutouts consists of one INA190AXIRSW device (where x is 1, 2, 3, 4, and 5) and test points for
external hardware connections, as well as pads to solder down optional circuitry. A sixth board includes a
guarding scheme to guard the input traces thus, preventing leakage current. This board has the INA190A5
as the installed test device.
2.1
Features
The INA190EVM PCB provides the following features:
•
Evaluation of all gain options through provided device boards
•
Ease of access to device pins with test points
•
Pads for optional filtering at the input pins, output pin, and reference pin
•
Pads for optional reference buffer driving circuit with SOT-23-5 op amp
•
Multiple input signal options including a method to solder the shunt resistor and safely measure current
up to 15 A
•
Low-current measurement panel with a voltage guarding plane to minimize leakage currents
