SBOS473I March 2009 – December 2018 TMP112
The TMP112 family requires pullup resistors on the SCL, SDA, and ALERT pins. The recommended value for the pullup resistors is 5 kΩ. In some applications the pullup resistor can be lower or higher than 5 kΩ but must not exceed 3 mA of current on any of those pins. A 0.01-μF bypass capacitor on the supply is recommended as shown in Figure 17. The SCL and SDA lines can be pulled up to a supply that is equal to or higher than V+ through the pullup resistors. To configure one of four different addresses on the bus, connect the ADD0 pin to either the GND, V+, SDA, or SCL pin.
