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 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…

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…
Part Number: TMP421 Other Parts Discussed in Thread: TMP441 Hi Expert,
My customer is currently using TMP421AIDCNR and they want to added TMP441AIDCNR as an alternative.
Do these two part can fully replaced each other without any BOM change and application…
