MAX40008/MAX40009 Evaluation Kit
Evaluates: MAX40008/MAX40009
General Description
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+)
installed that operates off a V
DD
supply between 1.7V
and 5.5V. The MAX40008/MAX40009 has a wide input
common mode voltage range from -0.2V to V
DD
+ 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.
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.
When using the MAX40008EVKIT# to evaluate the
MAX40009 (push-pull version), replace U1 (MAX40008)
with MAX40009 with jumper J1 removed.
Quick Start
Required Equipment
●
Three +5V DC power supplies
(V
DD
, V
IN+
, and V
PULL
)
●
Two digital multimeters (DMMs)
Procedure
The MAX40008/MAX40009 EV kit is fully assembled
and tested. Follow steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1)
Connect the positive terminal of a DC power supply
to the VDD test point and the ground terminal to the
GND test point.
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.
Connect the positive terminal of a DC power supply
to the INP test point and the ground terminal to the
GND test point.
Turn on the V
DD
power supply and set it to any
voltage between 1.7V and 5.5V.
Turn on the V
PULL
power supply and set it to any
voltage between 1.7V to 5.5V (MAX40008 only).
Do not need V
PULL
supply when MAX40009
(push-pull output) is used.
Turn on the IN+ power supply and set it to the desired
level.
Monitor the output using a DMM at the V
OUT
test
point and observe its response to varying voltage at
IN+. V
OUT
should be at logic-high (V
PULL
) when voltage
applied on IN+ is greater than V
IN-
and should be at
logic-low (0V) when the voltage applied on IN+ is less
than V
IN-
.

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.

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:

Use the MAX40008 output for logic-level translation
applications. Install jumper J1 and apply the desired
supply voltage level at V
PULL
. Resistors R5 and R6 set
the threshold voltage at IN-. Apply the signal to be level
translated at IN+. Note that the device’s output has an
absolute maximum of (-0.3V) to +6V. See
Table 1
for
jumper configurations.
The pullup supply voltage (V
PULL
) can be up to 6V.
For evaluating the MAX40008 on the MAX40009EVKIT#,
replace U1 (MAX40009ANT+) with MAX40008ANT+ and
install jumper J1 to connect to V
PULL
. When using the
MAX40008EVKIT#, to evaluate MAX40009 (push-pull
version), replace U1 (MAX40008) with MAX40009 with
jumper J1 removed.
