MAX038 Evaluation Kit
_______________General Description
The MAX038 evaluation kit (EV kit) is a high-frequency
function generator capable of producing accurate tri-
angle/sawtooth, sine, and square/pulse waveforms up
to 10MHz, using the supplied components. Output fre-
quency and duty cycle are easily adjusted with on-
board potentiometers. Removable jumpers select sine,
square, or triangle waveforms, or fix the duty cycle at
50%. The output is buffered with a MAX442 amplifier
capable of driving a 50鈩?coaxial cable. The MAX038
EV kit is fully assembled and tested.

______________________________EV Kit
_________________________Quick Start
The MAX038 EV kit is a fully assembled and tested
board. Follow these steps to verify board operation.
Do
not turn on the power supply until all connections
are completed.
1) Connect a +5V supply to the pad marked +5V.
Connect a -5V supply to the pad marked -5V.
Connect ground(s) to the GND pad.
2) Connect an oscilloscope to the BNC jack marked
OUTPUT through a terminated 50鈩?cable. The
MAX038 output prior to the amplifier stage may also
be monitored using an oscilloscope probe at the
OUT pad.
3) Place the shunt across pins 2 and 3 of JU4 for 50%
duty cycle. Place the shunt across pins 1 and 2 of
