SBOS473L March 2009 – July 2024 TMP112 , TMP112D
PRODUCTION DATA
The TMP112 family requires pullup resistors on the SCL, SDA, and ALERT pins. The recommended value for the pullup resistors is 5kΩ. In some applications the pullup resistor can be lower or higher than 5kΩ but must not exceed 3mA of current on any of those pins. A 0.01-μF bypass capacitor on the supply is recommended as shown in Figure 8-1 and Figure 8-2. 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. The TMP112Dx also provides four different address options when only ALERT pin is used.
