Quick Start

• MAXFILTERBRD

Required Equipment

• Suggested components (see Component List)

• 5V or 3V DC power supply (depending on the IC

installed)

• Function generator (e.g., HP 33120A)

• 2-channel digital oscilloscope (e.g., Tektronix TDS3012)

Procedure

Caution: Do not turn on power supply until all connec-

tions are completed.

1) Install all suggested components shown in the

Component List onto the MAXFILTERBRD.

2) If the installed IC is the MAX7408–MAX7411 or

MAX7418–MAX7421, connect the positive terminal of

the 5V supply to the VDD pad and the negative termi-

nal of the supply to the GND pad closest to the VDD

pad. If the installed IC is the MAX7412–MAX7415 or

MAX7422–MAX7425, connect the positive terminal

of the 3V supply to the VDD pad and the negative

terminal of the supply to the GND pad closest to the

VDD pad (see Figure 1). Set the function generator

to 4VP-P max, 2.2V offset (typ), and 1kHz sine wave,

and connect the signal to the IN pad.

3) Connect the first channel of the oscilloscope to the

IN pad.

4) Connect the second channel of the oscilloscope to

the OUT pad.

5) Connect the oscilloscope’s ground probe to any GND

pads.

6) Turn on the power supply.

7) Verify the output on the OUT pad.
