MAX14430–MAX14432 Evaluation Kit

Quick Start

Required Equipment

● MAX14430FS, MAX14431FS, or MAX14432FS EV kit

● Two DC power supplies with output range of 1.71V

to 5.5V

● Signal/function generator

● Oscilloscope

Procedure

The MAX14430FS, MAX14431FS, and MAX14432FS

EV kits are fully assembled and ready for evaluation. For

manual verification follow the steps below to verify board

functionality:

1) Verify jumper settings. See Table 2 for all shunt positions.

• J1 and J2 are closed.

• Jumper ENA is either in 1-2 position if U1 ENA (pin

7) has active-high polarity, or in 2-3 position if U1

ENA

(pin 7) has active-low polarity.

• Jumper ENB is in 1-2 position.

2) Connect one DC power supply between the EV kit’s

TP_VDDA and TP_GNDA test points; connect the

other DC power supply between TP_VDDB and TP_

GNDB test points.

3) Set both DC power supply outputs between 1.71V

and 5.5V, and then enable the power supply outputs.

Note: It is also possible to power the EV kits from a

single power supply to test electrical parameters but

this invalidates the digital isolation of the IC.

4) Connect the signal/function generator to the SMA

connector or test point of side A and observe the

isolated signal on the corresponding side B output,

using an oscilloscope.
