DS4424 - 7-Bit Sink/Source Current DAC

Download the DS4424 datasheet PDF. This datasheet also covers the DS4422 variant, as both devices belong to the same 7-bit sink/source current dac family and are provided as variant models within a single manufacturer datasheet.

General Description

The DS4422 and DS4424 contain two or four I2C programmable current 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 I2C interface.

The current DAC outputs power up in a high-impedance state.

Key Features

  • Two (DS4422) or Four (DS4424) Current DACs.
  • Full-Scale Current 50μA to 200μA.
  • Full-Scale Range for Each DAC Determined by External Resistors.
  • 127 Settings Each for Sink and Source Modes.
  • I2C-Compatible Serial Interface.
  • Two Address Pins Allow Four Devices on Same I2C Bus.
  • Low Cost.
  • Small Package (14-Pin, 3mm x 3mm TDFN).
  • -40°C to +85°C Temperature Range.
  • 2.7V to 5.5V Operating Range Pin Configura.
