Address configuration for STTS75, STDS75, STLM75 and STCN75

temperature sensors

The STTS75, STDS75, STLM75 and STCN75 all are digital temperature sensors with 3

address lines. There are 8 possible addresses for these sensors. SW2 corresponds to A0,

SW3 corresponds to A1 and SW4 corresponds to A2 address lines of the sensors. Below

are the allowed addresses and their settings for STTS75, STDS75, STLM75 and STCN75:

●

Address 1 = 0x90, => SW4 = 0, SW3 = 0, SW2 = 0

●

Address 2 = 0x92, => SW4 = 0, SW3 = 0, SW2 = 1

●

Address 3 = 0x94, => SW4 = 0, SW3 = 1, SW2 = 0

●

Address 4 = 0x96, => SW4 = 0, SW3 = 1, SW2 = 1

●

Address 5 = 0x98, => SW4 = 1, SW3 = 0, SW2 = 0

●

Address 6 = 0x9A, => SW4 = 1, SW3 = 0, SW2 = 1

●

Address 7 = 0x9C, => SW4 = 1, SW3 = 1, SW2 = 0

●

Address 8 = 0x9E, => SW4 = 1, SW3 = 1, SW2 = 1
