INA223EVM Hardware Overview

The INA223EVM hardware setup involves connecting the two EVM PCBs together, applying power,
connecting the USB cable, and setting the jumpers. This section describes the details of this procedure.
3.1 Electrostatic Discharge Warning
Many of the components on the INA223EVM are susceptible to damage by electrostatic discharge (ESD).
Customers are advised to observe proper ESD handling precautions when unpacking and handling the
EVM, including the use of a grounded wrist strap at an approved ESD workstation.
3.2 Connecting the Hardware
To connect the INA223 test board and the SM-USB-DIG Platform together, gently slide the male and
female ends of the 10-pin connectors together. Make sure that the two connectors are completely pushed
together; loose connections may cause intermittent operation.
3.3 Connecting Power
After the EVM and SM-USB-DIG are joined, as shown in
configuration to be measured. Typically, setup involves a high- or low-side load and a shunt resistor
across V and V
IN+ IN–
The power supply for V
needed depends on your testing needs.
