Evaluates: MAX40008/MAX40009MAX40008/MAX40009 Evaluation Kit
General DescriptionThe 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 VDD supply between 1.7V and 5.5V. The MAX40008/MAX40009 has a wide input common mode voltage range from -0.2V to VDD + 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.

Ordering Information appears at end of data sheet.
Quick StartRequired Equipment
Three +5V DC power supplies (VDD, VIN+, and VPULL)
Two digital multimeters (DMMs)
ProcedureThe 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.
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.
3) Connect the positive terminal of a DC power supply to the INP test point and the ground terminal to the GND test point.
4) Turn on the VDD power supply and set it to any voltage between 1.7V and 5.5V.
5) Turn on the VPULL power supply and set it to any voltage between 1.7V to 5.5V (MAX40008 only). Do not need VPULL supply when MAX40009 (push-pull output) is used.
6) Turn on the IN+ power supply and set it to the desired level.
7) Monitor the output using a DMM at the VOUT test point and observe its response to varying voltage at IN+. VOUT should be at logic-high (VPULL) when voltage applied on IN+ is greater than VIN- and should be at logic-low (0V) when the voltage applied on IN+ is less than VIN-.

Detailed Description of HardwareThe 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.
Positive Hysteresis 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:For the MAX40008 (open-drain) output:

and R5 and R6 set the threshold voltage at IN- input as follows:
+IN- DDR5

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.
Logic Level TranslationUse the MAX40008 output for logic-level translation applications. Install jumper J1 and apply the desired supply voltage level at VPULL. 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 (VPULL) can be up to 6V.For evaluating the MAX40008 on the MAX40009EVKIT#, replace U1 (MAX40009ANT+) with MAX40008ANT+ and install jumper J1 to connect to VPULL. When using the MAX40008EVKIT#, to evaluate MAX40009 (push-pull version), replace U1 (MAX40008) with MAX40009 with jumper J1 removed.
