Applications Information
Power-Supply Decoupling
To achieve best results, it is recommended that the
power supplies are decoupled with a 0.01μF or a 0.1μF
capacitor. Use high-quality, ceramic, surface-mount
capacitors, and mount the capacitors as close as pos-
sible to the voltage supplies and GND pins to minimize
lead inductance.
SDA and SCL Pullup Resistors
SDA is an open-collector output on the DS1882 that
requires a pullup resistor to realize high logic levels. A
master using either an open-collector output with a
pullup resistor or a push-pull output driver can be uti-
lized for SCL. Pullup resistor values should be chosen
to ensure that the rise and fall times listed in the
AC
Electrical Characteristics
