MAX9633 Evaluation Kit
• MAX9633 EV kit
• ±15V, 40mA DC power supply (PS1)
• +1V precision voltage source
• Digital multimeter (DMM)
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Connect the positive terminal of the +15V supply to
2) Connect the positive terminal of the precision
3) Install a shunt on jumper JU1 to short INA- to GND.
4) Connect the DMM to monitor the voltage on the OUTA
5) Turn on the Q15V power supply.
6) Apply +1V from the precision voltage source. Observe
7) Repeat steps 2–7 to evaluate OUTB.
The MAX9633 EV kit provides a proven layout for the
MAX9633 dual, low-noise, low-distortion op amp to
support multiple op-amp configurations. The EV kit
accepts a +4.5V to +36V single-supply voltage, or a
Q2.25V to Q18V dual-supply voltage.
Jumpers JU1–JU4 are provided to allow flex-
ibility in grounding inputs for multiple op-amp con-
figurations. When a shunt is installed on the jumper, the
corresponding input pad is referenced to ground. See
Table 1 for the JU1–JU4 configuration. See the Op-Amp
Configuration section for more information regarding EV
kit configuration.

*Default position.
To configure op-amp U1-A as an inverting amplifier,
replace R2 and R4 with the desired 1% gain-setting
resistors, install a shunt on jumper JU2, and feed a
voltage V
a shunt on JU2 to ground the INA+ input in this
configuration. The output voltage is given by the
following equation:
The offset voltage V
To configure op-amp U1-B as an inverting amplifier,
replace R7 and R9 with the desired 1% gain-setting
resistors, install a shunt on jumper JU4, and feed a
voltage V
a shunt on JU4 to ground the INB+ input in this
configuration. The output voltage is given by the
following equation:
The offset voltage V
To configure op-amp U1-A as a noninverting amplifier,
replace R2 and R4 with the desired 1% gain-setting
resistors, replace R3 with a 0I resistor, install a shunt on
jumper JU1, and feed a voltage V
and INA- pads. Install a shunt on JU1 to ground the INA-
input in this configuration. The output voltage is given by
the following equation:
To configure op-amp U1-B as a noninverting amplifier,
replace R7 and R9 with the desired 1% gain-setting
resistors, replace R8 with a 0I resistor, install a shunt on
jumper JU3, and feed a voltage V
