MAX9644/MAX9645/MAX9646 Evaluation Kits
Evaluate: MAX9644/MAX9645/MAX9646
Quick Start
Detailed Description of Hardware
The MAX9644/MAX9645/MAX9646 EV kits are fully
assembled and tested PCBs that evaluate the MAX9644/
MAX9645/MAX9646 single comparators. The MAX9644
is an open-drain noninverting single comparator, the
MAX9645 is an open-drain inverting single compara-
tor, and the MAX9646 is a push-pull noninverting single
comparator. All EV kits have an internal reference voltage
of +0.2V, require VCC between +1V to +5.5V to operate,
and have a common -0.3 to +5.5V input voltage (IN) range.
Recommended Equipment
•ꢀ MAX9644, MAX9645, or MAX9646 EV kit
•ꢀ Two -5V DC power supplies (VCC, IN)
•ꢀ Optional third +5V DC power supply (EXT for
MAX9644/MAX9645 only)
•ꢀ Digital multimeter (DMM)
Procedure
The EV kits are fully assembled and tested. Follow the
steps below to verify board operation. Caution: Do not
turn on the power supply until all connections are
completed.
VCC Supply Selection
The VCC PCB pad on the EV kits is used to supply a +1V
to +5.5V VCC supply to the IC.
The EV kits can evaluate both 4-bump UCSP (U1) and
5-pin SOT23 (U2) packages. The EV kit offers the option
to power up U1 or U2 separately though configuration of
jumper JU1. See Table 1 for power-up options.
1) Verify that a shunt is installed on pins 1-2 of jumper JU1.
2) Connect the positive terminal of a DC power supply to
the VCC PCB pad and the ground terminal to the GND
PCB pad.
EXT PCB Pad
The EXT PCB pad on the EV kits can be used as an
external source to pull the outputs high through resistors
R1 or R2 when open-drain versions of the parts are used.
3) Connect the positive terminal of a DC power supply to
the IN PCB pad and the ground terminal to the GND
PCB pad.
4) Connect the positive terminal of a DC power supply to
the EXT PCB pad and the ground terminal to the GND
PCB pad. (MAX9644/MAX9645 only)

5) Turn on the VCC power supply and set it to the
desired level.

8) Monitor the output using a DMM at the OUT1 PCB
pad, and study its response to varying voltage at IN.
