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.

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 ) 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.

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

Evaluation Kits

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.

Detailed Description of Hardware

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.

Remove R3 and eliminate V

if evaluating the

PULL

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.

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:

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.

Hysteresis =

× VCC

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.
