The INA193EVM provides basic functional evaluation of the INA193. The fixture layout is not intended to
be a model for the target circuit, and is not laid out for electromagnetic compatibility (EMC) testing.
The layout of the INA193EVM PCB provides the following features:
•
Ease of access to all device pins
•
Multiple input signal options
•
Optional surface-mount shunt
•
Optional input filter
•
Evaluate with and without a shunt resistor:
–
The INA193EVM measures differential voltage both with and without a shunt resistor. Connect both
sides of an external shunt resistor to measure current, or omit the shunt resistor and apply a
differential voltage directly to the device input.
•
INA19x family compatibility:
–
INA193 can be desoldered and replaced with the INA194 or INA195 to evaluate other gains
available in this product family.
–
INA196, INA197, and INA198 are the same devices in the same package, but with different pinouts.
The corresponding gains of the INA193 (20 V/V), INA194 (50 V/V), and INA195 (100 V/V) serve as
evaluation modules for those products as well.
Refer to the
INA19x product data sheet
for comprehensive information about this family of current-shunt
monitor devices.
