TMP117EVM: Using couple of TMP117EVM for the addresses 0x48 and 0x49

Vignesh Selvaraj

Part Number: TMP117EVM

Hello,

I recently bought a couple of TMP117EVM boards and I want to use them both in I2C. By default, they come with the ADDO pin grounded with a jumper resistor R16. In order to set the other TMP117EVEM to the address 0x49, I am supposed to jump the pins for R15 and remove the 0ohm R16 resistor right? so that the ADDO pin becomes V+

Thank you for your time

Hi Vignesh,

Thank you for your post.

You're correct. To change the address on the TMP117EVM you can move the 0 ohm resistor from R16 to R15, that would connect the ADD0 pin to Vdd rather than ground and set the address as 0x49.
