DS4432

The current DAC outputs power up in a high-impedance state. The DS4432 contains two I2C programmable 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 features of DS4432 can be summarized as (1)two current DACs; (2)full-scale current 50A to 200A; (3)full-scale range for each DAC determined by external resistors; (4)127 settings each for sink and source modes; (5)I2C-compatible serial interface; (6)low cost; (7)small package (8-Pin SOP); (8)-40°C to +85°C temperature range; (9)2.7V to 5.5V operating range.

The absolute maximum ratings of DS4432 are (1)voltage range on VCC, SDA, and SCL; (2)relative to ground: -0.5V to +6.0V; (3)voltage range on FS0, FS1, OUT0, OUT1 relative to ground: -0.5V to (VCC + 0.5V); (4)(Not to exceed 6.0V.)operating temperature range: -40°C to +85°C; (5)storage temperature range: -55°C to +125°C; (6)soldering temperature: refer to the IPC/JEDEC.
