TMP422: TMP422

Part Number: TMP422

Hi,  NOTE:  my application is using temperature diodes.   I am having repeatability issues,  Sometimes the addressing on 4 devices is not working ( works on only first one ).  All your diagrams only show a transistor application.  When using diodes, I assume the crossing of Anode and Cathode connection works the same as tranistors to set the address on power up.  Sometimes it works on mutliple addrs and sometimes not.  Also I am getting garbage data back but other times very repeatable expected temperatures.   Maybe noise problems ?   How important is the Series resistors and diff filter Caps ?  I am not using either.
