TMP1075N Typical Application

The TMP1075 can measure the PCB temperature of the location where the user mounts the device. The TMP1075 features two-wire SMBus and I 2 C interface compatibility, with the TMP1075 allowing up to 32 (TMP1075N: 4) devices on one bus. The TMP1075 requires a pullup resistor on the SDA pin, and if needed, on the SCL and ALERT pins. A 0.01-μF bypass capacitor is also required (see Figure 8-1 ).
