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
  • Low Cost
  • 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
