The INA2290EVM provides a basic functional evaluation of the INA2290. 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 INA2290EVM
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
. Each PCB cutout has one INA2290A
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.
3.1 Features
The INA2290EVM 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 INA2290 and the available gain options.
