SNIA038 December 2020 TMP139
Footprints for R1 and R2 can be used to set the address of the TMP139. Only one of these footprints should be populated at a time with a 0-Ω resistor. R1 will tie the SA pin to VDDSPD and encode the serial address as 7'b0110111. R2 will tie the SA pin to GND and encode the serial address as 7'b0010111.
