3.2.2.2 Jumper Configuration

The following table describes the functionality of the jumpers.

Table 3-13. Jumper Configuration
Jumper	Label	Default Setting	Function
J4	3V3	Closed	3.3V current measurement
J5	5V	Closed	5V current measurement
J6	SHDN	Open	To enable 3.3V and 5V converters despite SHDN command
J7	BACK-UP	Closed	3V3_BACK-UP current measurement
J8	VDDOUT	Closed	VDDOUT current measurement
J9	VREFP Selection	Closed	VREFP selection between internal or external voltage reference. Opened = Internal voltage reference¹ Closed = External voltage reference
J15	ERASE	Open	Erase pin configuration

Note:

Warning: If the ADC is configured (via SW) to use the internal voltage regulator as positive reference (VREFP), the jumper must be removed to avoid a short circuit.
