MAX9060–MAX9065 Evaluation Kits

Quick Reference
Recommended Equipment
Before beginning, the following equipment is needed:
• Two +5V DC power supplies (VCC/REF, IN)
• Optional third +5V DC power supply (EXT for
MAX9060–MAX9063 only)
• One digital multimeter (DMM)
Procedure
The MAX9060–MAX9065 EV kits are fully assembled
and tested. Follow the steps below to verify board oper-
ation. Caution: Do not turn on the power supply until
all connections are completed.
1) Verify that a shunt is installed on pins 1-2 of jumper
JU1.
2) Connect all power-supply ground terminals to a
GND pad.
3) Connect the positive terminal of a DC power supply
to the VCC/REF pad.
4) Connect the positive terminal of a DC power supply
to the IN pad.
5) Connect the positive terminal of a DC power supply
to the EXT pad (MAX9060–MAX9063 only).
6) Turn on the VCC/REF power supply and set it to the
desired level.
7) Turn on the IN power supply and set it to the
desired level.
8) Turn on the EXT power supply and set it to the
desired level (MAX9060–MAX9063 only).
9) Monitor the output using a DMM at the OUT1 pad,
and study its response to varying voltages at IN.
Detailed Description of Hardware
The MAX9060–MAX9065 EV kits are fully assembled
and tested PCBs that evaluate the MAX9060–MAX9064
single comparators and the MAX9065 window detector
comparator. The MAX9060/MAX9061 EV kits require an
external reference (REF) voltage between 0.9V and
5.5V, while the MAX9062/MAX9063/MAX9064 EV kits
have an internal reference voltage of 0.2V. The MAX9065
comes preprogrammed with trip points at 3V and 4.2V.
The MAX9062–MAX9065 require VCC between 1V to
5.5V to operate. All EV kits have a common -0.3 to
+5.5V input voltage (IN) range.
VCC/REF Supply Selection
The VCC/REF pad is used to supply either a 0.9V to
5.5V reference voltage (MAX9060/MAX9061) or a 1V to
5.5V VCC supply (MAX9062–MAX9065) to the IC.
The MAX9060–MAX9065 EV kits can evaluate both 4-
bump UCSP (U1) and 5-pin SOT23 (U2) packages. The
EV kits offer the option to power up U1 or U2 separately
though configuration of jumper JU1. See Table 1 for
power-up options.
EXT Pad
The EXT 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.
