4.1.1 Step 1: Set the I C Address
The first step to configuring the INA260 from the EVM GUI is setting up communication. As indicated by
2-2, the address bits A0 and A1 may represent up to 16 different INA260 devices communicating over a single
2
I C bus, where each device is identified by a unique target address. Therefore, step 1 involves selecting the
correct A0 and A1 values that represent the target address of the INA260 installed on the EVM. In other words,
the states of A0 and A1 in the GUI must match the jumper settings chosen for J2 and J3 on the EVM. The
equivalent hexadecimal value of the target address is displayed in the box labeled I
4.1.2 Step 2: Configure Operation
The INA260 offers multiple options for controlling the measurement process, including sequencing, triggering,
averaging, as well as a power-down function. The associated control parameters can be specified in this section
of the GUI.
Figure 4-3 shows the options available under the Operating Mode menu. The default operating mode is Shunt
and Bus, Continuous, which configures the INA260 to continuously measure the shunt current and bus voltage
in serial order. The user can also set the INA260 to only measure the shunt current or bus voltage, but most
applications benefit from measuring both signals.
For maximum functionality, select a Shunt and Bus operating mode, as shown in
Selecting any of the manual trigger modes allows the INA260 to only take measurements when the user clicks
the Write All Reg button.
The Power Down mode stops all measurements from taking place until the operating mode changes again. The
device remains attached to power but draws minimal supply current.
The Averaging Mode menu allows the user to select a desired number of samples for the INA260 averaging
feature. This step configures the INA260 to compute and store the average value of the specified number of
samples in the output register. The default value is 1.
