Evaluation Kits
Evaluate: MAX40000
MAX40001
General Description
Procedure
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+
installed that operate off a V
CC
supply between 1.7V and
5.5V, an internal reference voltage of 1.252V, and have a
wide -0.2V to +5.7V input voltage (V
IN
) range. These EV kits
demonstrate the MAX40000ANT12+/MAX40001ANT12+
in an ultra-small, 1.1mm x 0.76mm, 6-bump wafer-level
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.
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+.
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.
3) Connect the positive terminal of a DC power supply
to the INP test point and the ground terminal to the
GND test point.
4) Use a wire to short INM test point and V
REF
test point
to connect voltage reference output (1.252V, default)
to inverting input.
5) Turn on the V
CC
power supply and set it to any voltage
between 1.7V to 5.5V.
6) Monitor the output voltage at the VREF test point
using DMM. This should be 1.252V (default) when either
the MAX40000ANT12+/MAX40001ANT12+ is used.
7) Turn on the V
PULL
power supply and set it to any voltage
between 1.7V to 5.5V (MAX40001 only). Do not need
V
PULL
supply when MAX40000 (push-pull output) is
used on the MAX40001 EV kit.
8) Turn on the INP power supply and set it to the desired
level.
9) Monitor the output using a DMM at the VOUT test point
and study its response to varying voltage at INP. Ideally,
voltage at the VOUT test point of the MAX40001 EV kit
should be at logic-high (V
PULL
) when voltage applied on
INP is greater than 1.252V and should be at logic-low
(0V) when voltage applied on INP is less than 1.252V.
10) While, on the MAX40000 EV kit, the voltage on the
VOUT test point will be at V
CC
when the voltage on INP
is greater than 1.252V, it should be at GND when the
voltage applied on INP is less than 1.252.

Detailed Description of Hardware
Evaluate: MAX40000
MAX40001
The VPULL test point on the MAX40001 EV kit is utilized
to apply a pullup supply voltage between 1.7V to 5.5V
for the open-drain output devices for proper operation.
Remove R3 and eliminate V
PULL
if evaluating the
comparators with the push-pull output (MAX40000) on the
MAX40001 EV kit.
The MAX40000 EV kit, by default, comes with the
MAX40000ANT12+. If the user would like to evaluate the
MAX40001 on the MAX40000 EV kit, the user should
provide a pullup resistor to supply voltage on the VOUT
test point.
The MAX40001 EV kit, by default, comes with the
MAX40001ANT12+. If the user would like to evaluate the
MAX40000 on the MAX40001 EV kit, the user should
remove jumper J1 to the pullup resistor on the output pin.
The MAX40000/MAX40001 EV kits are fully assembled
and tested PC boards that evaluate the 6-bump WLP
MAX40000ANT12+/MAX40001ANT12+ push-pull/open-
drain output comparators, respectively. These EV kits require
a 1.7V to 5.5V supply voltage for normal operation and can
be used to evaluate all other MAX40000/MAX40001 parts
that come with a WLP.
These EV kits allow users to add external hysteresis in
addition to the 4mV internal hysteresis through the addition
of appropriate resistors on the R2 and R1 pads provided on
the EV board. The amount of hysteresis added is given by
the equation below, based on R1, R2 values:

These EV kits also allow users to apply an internal voltage
reference to either the IP or IN input pins of the comparator by
installing resistor components on R4, R5, and R6 pads.
R4 and R5 resistor combination can be used if a voltage-
divided version voltage of internal voltage reference is
needed in the application.
