Applications Information
Power-Supply Decoupling
To achieve best results, it is recommended that the power
supply is decoupled with a 0.01FF or a 0.1FF capacitor.
Use high-quality, ceramic, surface-mount capacitors,
and mount the capacitors as close as possible to the
VCC and GND pins to minimize lead inductance.
SDA and SCL Pullup Resistors
SDA is an open-collector output on the device that
requires a pullup resistor to realize high logic levels. A
master using either an open-collector output with a pul-
lup resistor or a push-pull output driver can be used for
SCL. Pullup resistor values should be chosen to ensure
that the rise and fall times listed in the I2C AC Electrical
Characteristics table are within specification.
