Hi
I would like to ask you what is the different between LM75x and TMP75x.
My understanging is,
- TMP75x is modified version of LM75x.
- We can replace LM75x with TMP75x.
- As LM75C has already discontinued, we should use TMP75C instead of LM75C.
Is this correct?
Thank you in advance.
Suzuki-san,
The LM75 is the original temperature sensors from National Instruments. The TMP75A is TI's version of it and is completely pin to pin compatible. The TMP75B & TMP75C are our newest versions enabling support for 1.8V supplies & communications, lower current consumption, and faster conversion speeds. The TMP75C provides an alternative register set to provide drop-in compatibility to some of our competition that did not follow the industry standard LM75 registers.
Below is a comparision of the LM75A to the TMP75 family of temp sensors and their higher accuracy versions (TMP175 & TMP275). I've also included the TMP102 & TMP112 which are very popular due to their combination of small packaging, very low power, and high accuracy.
