General Description
The DS4422 and DS4424 contain two or four I2C pro-
grammable current DACs that are each capable of
sinking and sourcing current up to 200A. 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.
Applications
Power-Supply Adjustment
Power-Supply Margining
Adjustable Current Sink or Source
Features
Two (DS4422) or Four (DS4424) Current DACs
Full-Scale Current 50A to 200A
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
