_______________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

Ω coaxial cable. The MAX038

EV kit is fully assembled and tested.

___________________________Features

o 325kHz to 10MHz Operation

o Adjustable Duty Cycle

o 2.5V Reference Output

o TTL-Compatible SYNC Output

o Fully Assembled and Tested

____________________Component List

_________________________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

Ω 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
