After the Start condition, the transmitting IC accesses the slave IC by Slave address, and transmits the

data to each channel by two bites (Sub address and DAC data).

 Supply voltage terminal (Vcc) is also used for D/A converter upper reference voltage setting. If ripple or

spike is input this terminal, accuracy of D/A converter is down, So, when use this device, please connect

capacitor among Vcc to GND for stable D/A conversion.

 This IC’s output amplifier has an advantage to capacitive load, So, it’s no problem at device action when

connect capacitor ( 0.1 µF Max ) among output to GND for every noise elimination.
