DS18B20-PAR
PostPosted: Sun Jun 18, 2006 8:37 am     Reply with quote
Hi guys,
I'm using a DS18B20 in parasite power mode. I saw the new model DS18B20-PAR, which is the same but have the connection between the GND and Vcc pins within the component. So there the pin of Vcc is left without connection.

My surprise came when I tested the DS18B20-PAR in the same circuit where the DS18B20 was working, and the vaule I get always is 127.94 ºC. I have gone through the datasheet, and it seems than both of then should be compatible.
Ay ideas??
