TMP442: TMP442B

Part Number: TMP442

Hi, Support

       I have a question about the TMP442B I2C addressing.  From the datasheet, the address of the TMP442B is pre factory set address. 1001101b.

So, if I want to use two TMP442B in one board, how can I address them..  there is no address configuration pins.

    Thanks for the post - that is correct, there are two orderable part numbers for TMP442, (A and B) you would have to use one of each to have separate I2C addresses or use an I2C multiplexer part like below if you want to use one orderable PN on the temp sensor side:
