ISL76683 Light-to-Digital Output Sensor Evaluation 

Hardware/Software User Guide

Description

The ISL76683EVAL1Z evaluation board is an RoHS compliant 
evaluation board designed for exploring the operation of the 
ISL76683 light-to-digital output sensor. The evaluation board is 
an easy-to-use platform for testing most of the specifications 
and functionalities described in the 

ISL76683 datasheet

Evaluation Package

• Demo Board (Evaluation Board ISL76683EVAL1Z and USB 

Board ISLUSBCEVAL1Z, REV A), populated with all required 
components

• USB  2.0  Cable
• Evaluation Software (see

 “Tools and Support”

 on

 ISL76683 

device information page

)

• AN1657: “ISL76683 Light-to-Digital Output Sensor 

Evaluation Hardware/Software User Guide” (see 

“Technical 

Documentation”

 on

 ISL76683 device information page

)

System Requirements

• Windows 98/NT/2000/XP
• USB  Port

Hardware Setup

The PC and printed circuit board (PCB) should not be 
connected via the USB until after the evaluation software has 
been installed satisfactorily (see “Software Setup” on page 2).
To set up the hardware:

1. Connect the USB 2.0 cable first to the PC and then to the 

evaluation board. The USB cable is the only connector 
needed.

2. If a dialog appears asking about installing software for 

new-found hardware, click “Yes, this time only”.

The jumpers on the printed circuit board (PCB) are as shown in 
Table 1.
