I have a strange problem. I am reading two ADT75 via i2c, but ONE of the sensors fails on temperatures above approx. 34°C.
These guys are very small surface mounted chips, so in I soldered them with tiny copper wires on some small stripe-board. One is on address 0x048 the other one on 0x049 (Pin 7 (A0) connected to VDD). The other address pins are open.
I tested several values for Pull-up resistors. No change.
So did I killed one while soldering? DId someone encountered similar problems (even on other i2c devices)? Any other ideas?
Best regards, Carsten
