Other Parts Discussed in Thread: TMP461
Hello, I'm using the TMP468 to measure the temperature from 8 remote diodes. The only problem is that I have to disconnect the diodes periodically (there's a relay in the path to switch it to a different function) and when I do that, I always get back a temperature of 256C unless I either do a Reset (write to register 0x20) or I write to the configuration register (0x30). I have it setup to read continuously, but can you confirm that if the diode is disconnected for a while (100ms or more), it will continue to read as if it is OPEN even after it has been reconnected and is not OPEN? From what I can tell, it reads continuously until it encounters the diode being an open circuit at which point it quits reading temperatures from that diode until the chip is reset or reconfigured. Is that right or am I doing something wrong here? Thanks!
