Quick Start Setup and Use

Follow these procedures to set up and use the INA210-215EVM. For the following instructions, x = 0 to 5.
Step 1. Connect an external dc supply voltage between 2.7-V and 26-V to the V+ test point TPx01 or
TPx11, and connect ground reference of that supply to the GND test point TPx02 or TPx12.
The INA210-215 device output voltage is limited to 50 mV above ground to 200 mV below the
supply level.
Step 2. The REF pin is connected to GND in the default board. The voltage applied at the reference
input can vary depending on how the device is going to be used. Further details regarding the
use of the reference voltage are discussed later in this document.
Step 3. Connect the input.
3.1 Measurements
The INA210-215EVM allows the user to either simulate the voltage developed across a sense resistor
based on a given set of system conditions, or to connect it remotely to an existing shunt already included
in an example application.
To configure a measurement evaluation without a shunt, follow these procedures:
1. Connect a differential voltage to the IN+ (TPx03 or TPx13) and IN– (TPx04 or TPx14) test points. With
the reference voltage set at ground, ensure that the IN+ pin is the more positive of the two inputs.
2. Measure the output voltage at the OUT test point (TPx06 or TPx16).
NOTE: The output voltage is equal to the gain of the device multiplied by the differential voltage
measured directly at the device input pins.

INA210-215EVM Circuit

This section summarizes the INA210-215EVM components. For the following instructions, x = 0 to 5.
4.1 Rx05, Rx06, Cx03
Rx05 and Rx06 are factory-installed 0-Ω resistors. These resistors, in combination with Cx03, form an
input filter. These locations allow for 0805 surface-mount package size. Additional information regarding
the use of input filtering is provided in the INA210-215 product data sheet (SBOS437).
4.2 Cx05
Cx05 are 0.1-μF supply bypass capacitors.
