... Rev 1; 8/06 Two/Four-Channel, I General Description The DS4402 and DS4404 contain two and four I adjustable current DACs, respectively, that are each capable of sinking or sourcing current. Each output has 31 sink and 31 source settings that are programmed by 2 the I C interface. External resistors set the full-scale range and step size of each output ...

... I The DS4402/DS4404 respond to one of nine I addresses determined by the two tri-level address inputs. The three input states are connected to V connected to ground, or disconnected. To sense the disconnected state (Figure 2), the address inputs have weak internal resistors that pull the pins to mid-supply ...
