    Hello Eli,

    Both TMP513 and TMP423 support 3 channel inputs. You can use 9 TMP432 and 4 TMP513 devices on an I2C bus. On the other hand TMP175 is a local temperature sensor where in you can connect upto 27 different devices.

    Hope this is answers your question but please do let me know if have any more questions.

    Regards,

    Abhi

    Hello Abhi

    So all three devices can be used for temp sensor at three points on a board?

    what is your best recommendation based on above requirements?

    Hello Eli,

    Yes, you can use any one of the above or all three, it depends on you application requirements. So far I have only understood only 2 requirements from you 1. 3 channels 2. different I2C addresses.

    I will need more information to recommend a specific part because all 3 parts satisfy your requirement. If you are looking for a simplistic approach wherein you have the provision of measuring temperature at the site of interest and  don't want to worry about having a diode/transistor connections I would suggest you to take the TMP175 approach.

    I hope my answer has brought you clarity towards decision making.

    Best Regards,

    Abhi
