Part Number: TMP421 Hi team,
We are considering using the TMP421 to measure the temperature of our device. The device has TEMP_A (anode) and TEMP_K (cathode) pins for temperature measurement, with an internal diode embedded between them. We plan to…
Part Number: TMP421 Per datasheet, a total of up to 3kΩ of series line resistance is cancelled. Is 3kΩ a combined series resistance connected externally to the D+, D– pins? Or is it a resistance connected externally to each of the D+, D– pins?
Part Number: TMP421 Tool/software: Hi AE,
A bout the TMP421, I had the question and need to confirm as below:
1. During the I2C communication process, changes the A0 and A1 will produce different I2C Address.
2. Why is half of VCC when A0/A1 Pin…

Please send me some TMP431A example code ( C code ) for reading the temperature by I2C bus.
Thanks,

Part Number: TMP421 Hi Team,
I have a customer that is using the TMP421, and he is able to measure the temperature from the on-board sensor. The issue is that when he is accessing the remote sensor the readings are a fixed in-range value that is incorrect…
Part Number: TMP421 Other Parts Discussed in Thread: DXP Tool/software: Hello,
I want to confirm I am connecting and using an appropriate PNP transistor for remote sensing with the TMP421. I selected a 3906 PNP transistor, where I connected the emitter…
Part Number: TMP421 Other Parts Discussed in Thread: DXP , Hi,
The TMP421A reads temperature from the remote sensor, and the obtained values are all negative. We have tried swapping resistor and capacitor positions and values as per the datasheet, but…
