CCS/TMP112: PULLUP RESISTOR FOR MULTIPLE I2C SENSORS

TMP112: multiple temp sensors with same I2C bus

Part Number: TMP112
Other Parts Discussed in Thread: TMP468,

Team, 

If I use (3) TMP112 parts and (1) TMP468 part, can I use the same I2C bus?  I would assume putting the 468 ADD pin to ground.

    Hi Michael,

    Yes you can. You would simply need to connect the address pins on your 3 TMP112s such that the address did not conflict with the address option you chose for the TMP468.

    So if you connected the TMP468 address pin to ground, you would want to connect the A0 Pins of your TMP112s to V+, SDA, or SCL, ensuring all three were connected differently.
