Procedure
General Description
The MAX40000/MAX40001 EV kits are fully assembled
and tested. Follow steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed. By default, the MAX40000
EV kit comes with the MAX40000ANT12+.
The MAX40000 and MAX40001 evaluation kits (EV kits)
are fully assembled and tested PC boards that evaluate
the MAX40000 and MAX40001 single comparators with
internal voltage references, respectively. By default, the
MAX40001 EV kit has an open-drain output, while the
MAX40000 EV kit has a push-pull output. These EV
kits come with a MAX40000ANT12+/MAX40001ANT12+
1) Connect the positive terminal of a DC power supply
to the VDD test point and the ground terminal to the
GND test point.
2) Connect the positive terminal of a DC power supply to
the VPULL test point and the ground terminal to the
GND test point (not applicable for the MAX40000
EV kit). This is not necessary while evaluating the
MAX40000 on the MAX40001 EV kit. R3 needs to be
removed while using MAX40001 EV kit to evaluate
the MAX40000 push-pull version.

package (WLP) with 0.35mm bump spacing.
These EV kits can be used to evaluate the entire family
of MAX40000/MAX40001 with 6-bump WLP options.
Remove pullup resistor R3 on the MAX40001 EV kit
when evaluating the MAX40000 in place of the default
MAX40001 IC included in the MAX40001 EV kit.
3) Connect the positive terminal of a DC power supply
to the INP test point and the ground terminal to the
GND test point.
