MAX40016 Evaluation Kit
General Description
The MAX40016 evaluation kit (EV Kit) provides a proven
design to evaluate the MAX40016 wide dynamic range
current sense amplier. The MAX40016 integrates the
sense element, eliminating a bulky and costly external sense/
shunt resistor. The device measures four of decades of
current (from < 300µA to 3A) while maintaining a highly
accurate output reading. This EV kit demonstrates the
MAX40016 in a tiny, space-saving, 15-bump wafer-level
package (WLP).
The MAX40016 EV kit PCB comes with the
MAX40016ANL+ device installed.

MAX40016 Evaluation Kit
Procedure
The EV kit is fully assembled and tested. Follow the below
to verify board operation.
Caution: Do not turn on the power supply or the
electronic load until all the connections are made.
V
ISH
Testing
1) Set the DC power supply to +3.6V and turn it off. Connect
the positive terminal of the supply to the VDD banana
jack test point and the negative terminal of the supply
to the nearest GND banana jack test point.
2) Set the electronic load to sink 1A. Connect the positive
terminal of the electronic load to the VLD banana jack
test point and the negative terminal of the supply to
the nearest banana jack GND test point.
3) Connect DMM1 between V
ISH
and the nearest GND
test point.
4) Connect DMM2 between V
OUT
and the nearest GND
test point.
5) Verify all the shunts are in default positions as shown
in Table 1.
6) Enable the 3.6V supply voltage at V
DD
.
7) Turn on the electronic load and verify that the current
owing is equal to the set value of 1A.
8) Observe the output voltage from all digital voltmeter
displays. Verify that approximately, V
ISH
= 320mV,
and V
OUT
= 480mV.
9) Turn off the electronic load then turn off the V
DD
supply voltage.
V
ISM
Testing
1) To test the V
ISM
output, change JU0 from 2-1 to 2-3
position.
2) Remove the DMM1 and connect it between V
ISM
and
the nearest GND test point.
3) Set the electronic load to sink 50mA. Connect the
positive terminal of the electronic load to the VLD
banana jack test point and the negative terminal of
the supply to the nearest banana jack GND test point.
4) Enable the 3.6V supply voltage at V
DD
.
5) Turn on the electronic load and verify that the current
owing is equal to the set value of 50mA.
6) Observe the output voltage from all digital voltmeter
displays. Verify that, approximately, V
ISM
= 536mV,
and V
OUT
= 804mV.
7) Turn off the electronic load, then turn off the V
DD
supply voltage.
V
ISL
Testing
1) To test the V
ISL
output, change JU0 from 2-3 to 2-1
position, and change JU1 from 2-1 to 2-3 position.
2) Remove the DMM1 and connect it between V
ISL
and
the nearest GND test point.
3) Set the electronic load to sink 1mA.
4) Enable the 3.6V supply voltage at V
DD
.
5) Turn on the electronic load and verify that the current
owing is equal to the set value of 1mA.
6) Observe the output voltage from all digital voltmeter
displays. Verify that approximately, V
ISM
= 320mV,
and V
OUT
= 480mV.
