General Description

Features

♦ Two (DS4422) or Four (DS4424) Current DACs

The DS4422 and DS4424 contain two or four I C pro-

grammable 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

♦ Full-Scale Current 50µA to 200µA

♦ Full-Scale Range for Each DAC Determined by

programmed using the I C interface. The current DAC

External Resistors

outputs power up in a high-impedance state.

♦ 127 Settings Each for Sink and Source Modes

♦ I C-Compatible Serial Interface

Applications

♦ Two Address Pins Allow Four Devices on Same
