RECOMMENDED APPLICATION CIRCUIT
USAGE PRECAUTIONS
Supply Connections
Ensure that the VCC and VCCD have the same potential. VDD is the I
nals should have a pull-up connection to VDD.
Setting the Slave Address to 49h
When the ADS pin is open-circuit, the slave address is set to 49h. When open, however, a large external spike
noise or other interference can cause a malfunction. An external resistor should be connected to ADS as shown
in figure 4 for protection.
