General Description

The MAX22191 evaluation kit (EV kit) is a fully assembled

and tested circuit board that demonstrates the functionality

of the MAX22191 digital input in an optical isolator circuit.

The EV kit features two circuits: one for a 24V digital input

signal and one for a 48V input signal.

Features

● 24V and 48V Circuits for Easy Evaluation

● Proven PCB Layout

● Fully Assembled and Tested

Quick Start

Required Equipment

● MAX22191 EV kit

● 24V Digital signal generator

● Oscilloscope

Startup Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation:

1) Ensure that the jumpers are in the default position

(Table 1).

2) Connect the digital signal generator to the IN+ test

point (TP3) and IN- test point (TP4)

.

3) Connect the oscilloscope to the IN+ test point (TP3),

and the OUT (TP14) test point. Connect return terminals

to the IN- test point (TP4)

4) Set the digital signal generator to generate a 0V–

24V 2kHz pulse.

5) Turn on the digital signal generator.

6) Monitor the IN+ and OUT signals. Verify that the

OUT signal toggles as expected.
