s Technical Information

• I2C bus

1. DAC

1) Built-in 5 DAC controls and 8 switches

2) Incorporating auto-increment functions

(1) Sub address 0* : Auto-increment mode

(Data are inputted by the change of sub-address according to the transfer when data are sequentially transferred.)

(2) Sub address 8* : Data renewal mode

(Data are inputted with the same sub-address when data are sequentially transferred.)

3) I2C bus protocol

(1) Slave address: 10000000 (80H)

(2) Format (normal)

S Slave address A Sub address A Data byte A P

Start condition Acknowledge bit

Stop condition

(3) Auto-increment mode/data renewal mode

S Slave address A Sub address A Data 1 A Data 2 A

Data n A P

4) Typical data should be inputted at power on because initial state of DAC is not guaranteed.
