DS4422/DS4424

Two-/Four-Channel, I²C, 7-Bit Sink/Source

Current DAC

General Description

Beneﬁts and Features

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

The DS4422 and DS4424 contain two or four I C

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

● Full-Scale Current 50μA to 200μA

● Full-Scale Range for Each DAC Determined by

External Resistors

programmed using the I C interface. The current DAC

● 127 Settings Each for Sink and Source Modes

outputs power up in a high-impedance state.

● I C-Compatible Serial Interface

Applications

● Power-Supply Adjustment

● Power-Supply Margining

● Adjustable Current Sink or Source

● Two Address Pins Allow Four Devices on Same

I C 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
