Interface (Figure 2). The QuikEval software is available at:

Interface Design

The QuikEval interface consists of a Scan button which, 

when pressed, causes the software to poll every I

2

C ad-

dress one at a time and listen for an acknowledge. Every 

address that acknowledges is then listed in the Detected 

Address list box directly beneath the Scan button. Once 

the  addresses  are  detected,  the  software  determines 

which ones correspond to the LEDs on the demo board. 

At this point, clicking on the DAC Thru or DAC Translated 

light-up control will cause the corresponding LED on the 

demo board to illuminate. The Open Translator Tool but-

ton opens a tool that allows users to design an I

2

C bus 

using LTC4316 I

2

C devices in an easy to use graphical 

format. Figure 2 shows the results of selecting the Scan 

button  on  a  DC22117A  with  a  standard  configuration. 

The Detected addresses show the All Call address, the 

address of the DAC on the incoming I

2

C bus, the address 

of the translated output I

2

C bus, and the address of the 

on board EEPROM. The 0x12 [D1] Thru LED button has 

been selected and corresponds to the THRU LED on the 

DC2217A being illuminated.
