INA293EVM

Hardware
The INA293EVM provides basic functional evaluation of the INA293. 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
INA293EVM consists of one PCB with an option to cut out ten individual PCBs, one for each of the five
gain options (1 to 5) and the two different pin outs (A and B) listed in
. Be aware that because of
the different pinouts of the A and B versions, the layouts and test point locations are also different. Each of
the PCB cutouts consists of one INA293
Xn
device (where
X
is A or B and
n
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.

Features
The INA293EVM 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 5 A.
See the
for comprehensive information about the INA293 and the available gain
options.
