... Rev 0; 12/08 www.DataSheet4U.com Dual-Channel, I General Description 2 The DS4432 contains two I DACs that are each capable of sinking and sourcing current up to 200µA. Each DAC output has 127 sink and 127 source settings that are programmed using the interface. The current DAC outputs power high-impedance state ...

... When the R/W bit is 0 (such as in 90h), the master is indicating it will write data to the slave (91h in this case), the master is indicating it wants to read from the slave incorrect slave address is written, the DS4432 assumes the master is commu- 2 nicating with another I communication until the next START condition is sent ...
