MAX40008/MAX40009 Evaluation Kit
Evaluates: MAX40008/MAX40009
General Description
Quick Start
The MAX40008/MAX40009 evaluation kit (EV kit) is a
fully assembled and tested PC board that evaluates
the MAX40008/MAX40009 single comparator with shutdown
input. The MAX40009EVKIT# comes with a push-pull out-
put (MAX40009ANT+), while the MAX40008EVKIT# EV
kit comes with an open-drain output (MAX40008ANT+)
Required Equipment
● Three +5V DC power supplies
(V , V , and V
)

PULL
● Two digital multimeters (DMMs)

connections are completed.
and 5.5V. The MAX40008/MAX40009 has a wide input
common mode voltage range from -0.2V to V + 0.2V.
This EV kit demonstrates the MAX40008/MAX40009 in an
ultra-small, 0.73mm x 1.1mm, 6-bump wafer-level pack-
age (WLP) with 0.35mm bump spacing.

1) Connect the positive terminal of a DC power supply
to the VDD test point and the ground terminal to the
GND test point.
The EV kit can be used to evaluate both the
MAX40008 and MAX40009 with a 6-bump WLP. To
evaluate the MAX40008 (open-drain output version on
MAX40009EVKIT#), replace U1 (MAX40009) with the
MAX40008 with jumper J1 installed.
2) Connect the positive terminal of a DC power supply to
the VPULL test point and the ground terminal to the
GND test point when evaluating the MAX40008. This
is not necessary when evaluating the MAX40009.
When using the MAX40008EVKIT# to evaluate the
MAX40009 (push-pull version), replace U1 (MAX40008)
with MAX40009 with jumper J1 removed.
3) Connect the positive terminal of a DC power supply
to the INP test point and the ground terminal to the
GND test point.

Detailed Description of Hardware
The MAX40008/MAX40009 EV kit is a fully assembled
and tested PC board that evaluates the 6-bump WLP
MAX40009ANT+ open-drain output comparator, while
the MAX40008EVKIT# comes with an open-drain output
(MAX40008ANT+). The EV kit requires a 1.7V to 5.5V
supply voltage for normal operation. The EV kit can be
used to evaluate both the MAX40008 and MAX40009
offered in a WLP package.

and R5 and R6 set the threshold voltage at IN- input as

The EV kit allows user to add external hysteresis in addi-
tion to the 4mV internal hysteresis by usage of adding
appropriate resistors on R2 and R1 pads. When R1 and
R2 values are chosen in such a way that R1, R2 >> R3
(39kΩ) approximately greater 50x than R3, then the equa-
tions become:

The source providing the signal input at IN+ input should
be a low impedance source. High-impedance source
affects the trip points as the input resistance of the source
adds on to R1.
