Quick Start Setup and Use

Follow these procedures to set up and use the INA210-214EVM.
Step 1. Insert the device board to be evaluated into the U1 location. The U1 location allows the user
to either evaluate one of the provided device boards or install the test device directly on the
surface-mount pads in the U1 footprint.
Step 2. Connect an external dc supply voltage between 2.7V and 26V to the V+ terminal referenced
to the GND terminal of T3. The INA210-214 device output voltage is limited to 50mV above
ground to 200mV below the supply level.
Step 3. Connect the REF terminal of T3 to ground. The voltage applied at the reference input can
vary depending on how the device is to be used. Further details regarding the use of the
reference voltage are discussed later in this document.
Step 4. Connect the input.
This connection method allows the user to install a shunt resistor on the EVM and connect the
common-mode voltage and load to incorporate the test device directly into a sample application, as
Figure 2 shows. To configure a measurement evaluation with a shunt, follow these procedures.
1. Install a shunt resistor into the R2 location. If not using a surface-mount or through-hole shunt, please
refer to Section 3.1 for a summary of R1 component specifications.
2. Connect the common-mode voltage to the V
IN
terminal of T1.
3. Connect load to the Load terminal of T1.
