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.

Note:

For maximum functionality, select a Shunt and Bus operating mode, as shown in Figure 4-3.

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.
