TMP461: Should D+ and D- should be connected to GND or Connected to each other when Remote Sensor NOT used in TMP461 ?
Part Number: TMP461
D- is connected to GND internally? why the measured resistance between D- and Pin 6 is not zero, about 1ohm.
so if I connect D+ to D-, it have the same performance with only D+ connected to GND and D- Pin is NC?
If you connect the D+ and D- pin to each other you will not be able to measure a remote temperature value. If you are only using the TMP461 as a local temperature sensor, you will not see a loss of local temperature accuracy if you connect D+ and D- together or only D+ connected to GND and D- floating.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Yes, no request for remote function.
please explain why the resistance between D- and GND is 1ohm ，while you confirmed D- is connected to GND internally.

There is parasitic resistance between the two pins which is probably what you are seeing.
