DS4432U+

The DS4432U+ is a low cost, dual channel, 7bit I2C adjustable sink/source current DAC (digital to analogue converter) in 8 pin µSOP package. It contains two I2C programmable current DACs which are capable of sinking or sourcing current up to 200μA. Each DAC output has 127 sink and 127 source settings that are programmed using I2C interface. The current DAC outputs power up in a high impedance state. The DS4432 is used in power supply adjustment and power supply margining applications.

• Supply voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to 85°C
• 50μA to 200μA full scale current
• SCL clock frequency of 400KHz
• Supply current of 150μA at VCC = 5.5V
• Full scale range for each DAC determined by external resistors
