2 Maxim Integrated
Evaluates: MAX9632
MAX9632 Evaluation Kit
Quick Start
Required Equipment
• MAX9632 EV kit
• ±15V, 40mA DC power supply (PS1)
• +1V precision voltage source
• Digital multimeter (DMM)
Procedure
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
the VCC pad and the GND terminal to the GND pad.
Connect the negative terminal of the -15V supply to
the VEE pad and the GND terminal to the GND pad.
The power supplies should be off.
2) Connect the positive terminal of the precision voltage
source to the IN- pad. Connect the negative terminal
of the precision voltage source to the IN+ pad.
3) Install a shunt on jumper JU2 to short IN+ to GND.
4) With the 100I feedback resistor and on-board 100I
resistor, the gain is -1 (inverting configuration).
5) Connect the DMM to monitor the voltage on the OUT
pad.
6) Turn on the Q15V power supply.
7) Apply 1V from the precision voltage source. Observe
the output at the OUT pad on the DMM. OUT should
read approximately -1V.
Detailed Description of Hardware
The MAX9632 EV kit provides a proven layout for the
MAX9632 low-noise op amp to support multiple op-amp
configurations. The device accepts a single-supply
voltage from +4.5V to +36V, or a dual-supply voltage
from Q2.25V to Q18V.
Jumper Selection
Jumpers JU1 and JU2 are provided to allow flexibility
in grounding inputs for multiple op-amp configurations.
When a shunt is installed on JU1 or JU2, the corre-
sponding input pad is referenced to ground. See Table
1 for JU1 and JU2 configuration. See the Op-Amp
Configuration section for more information regarding EV
kit configuration.
Shutdown Mode (SHDN)
Jumper JU3 controls the shutdown mode (SHDN) of the
device. When SHDN is pulled low, the device is enabled.
When the SHDN pin is pulled high, the device is
disabled. See Table 2 for JU3 configuration.
