Description

The DS4402 and DS4404 contain two and four I²C 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 the I²C interface. External resistors set the full-scale range and step size of each output.

Key Features		Applications/Uses
Two (DS4402) or Four (DS4404) Current DACs Full-Scale Range for Each DAC Determined by External Resistors 31 Settings Each for Sink and Source Modes I²C-Compatible Serial Interface Two Three-Level Address Pins Allow Nine Devices on Same I²C Bus Small Package (14-Pin TDFN) -40°C to +85°C Temperature Range 2.7V to 5.5V Operation		Adjustable Current Sink or Source Power-Supply Adjustment Power-Supply Margining
