Principio de funcionamiento

The DS4432 provides two independent 8-bit current DACs. Each 8-bit value consists of a 7-bit magnitude and a 1-bit sign bit that determines current direction (source or sink). The full-scale current is set by an external resistor on the FS pin (IFS = 0.793V / RFS). The DAC output current is then IOUT = (Code/127) x IFS x Direction. This bidirectional capability makes the DS4432 ideal for offset trimming – it can add or subtract a small current to null offsets in analog circuits. I2C interface allows software-controlled adjustment. Power-on reset sets both outputs to zero current.

Aplicaciones

  • Offset trimming
  • Bias adjustment
  • Sensor calibration
  • Laser diode control
