General Description

The MAX4885E evaluation kit (EV kit) is an assembled

and tested circuit board that contains all the compo-

nents necessary to evaluate the MAX4885E IC. The

MAX4885E is a 1:2 switch for VGA signals. The EV kit

can be powered from the 5V DC delivered through the

VGA cable. The EV kit can also operate from an exter-

nal 5V ±10% DC power supply.

Features

♦ 1:2 Switch for VGA Signals

♦ VGA Connections and Power

♦ Single 5V DC Power Supply (VIN)

♦ LED Indicators for Switch Connections

♦ Evaluates the MAX4885E in a 4mm x 4mm x 0.8mm,

24-Pin TQFN Package with an Exposed Pad

♦ Lead(Pb)-Free and RoHS Compliant

♦ Fully Assembled and Tested
