19-5967; Rev 0; 7/11 MAX9644/MAX9645/MAX9646 Evaluation Kits Evaluate: MAX9644/MAX9645/MAX9646 General Description Features The MAX9644/MAX9645/MAX9646 evaluation kits (EV kits) are fully assembled and tested PCBs that evaluate the MAX9644/MAX9645/MAX9646 single comparators. All EV kits have a common internal reference voltage of +0.2V, operate from a +1V to +5.5V power supply (VCC), and have a common -0.3V to +5.5V input voltage (IN) range. S -0.3V to +5.5V Input Voltage Range The EV kits are configured to evaluate both the 4-bump UCSPK (installed) and an optional 5-pin SOT23 (to do so, request a free MAX9644/MAX9645/MAX9646 SOT23 IC sample when ordering the EV kits). S Proven PCB Layout S +1V to +5.5V VCC Range S +0.2V Internal Reference Voltage S Evaluates 4-Bump UCSP and Optional 5-Pin SOT23 Packages S Fully Assembled and Tested Ordering Information appears at end of data sheet.

The MAX9644 is an open-drain noninverting single comparator, the MAX9645 is an open-drain inverting single comparator, 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. • 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. 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. 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. 6) Turn on the IN power supply and set it to the desired level. 7) Turn on the EXT power supply and set it to the desired level (MAX9644/MAX9645 only). 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. 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. Table 1. Jumper JU1 Functions SHUNT POSITION VCC/REF PAD 1-2* Powers U1 (UCSP) sub circuit 2-3 Powers optional U2 (SOT23) sub circuit *Default position. 8) Monitor the output using a DMM at the OUT1 PCB pad, and study its response to varying voltage at IN. __________________________________________________________________ Maxim Integrated Products   2 MAX9644/MAX9645/MAX9646 Evaluation Kits Evaluate: MAX9644/MAX9645/MAX9646 Figure 1.
