DAC161P997CISQ/NOPB

Data Acquisition

16-bit DAC4-20 mAcurrent loopSWIFHARTWQFN-16

DAC161P997CISQ/NOPB is a 16-bit current-loop DAC for precision industrial 4 mA to 20 mA transmitters using an external NPN transistor.

Best for

  • Precision 4 mA to 20 mA loop transmitters
  • Isolated industrial transmitters using pulse-transformer SWIF
  • HART-capable transmitter designs

Avoid if

  • A direct high-voltage loop interface without external regulation is required
  • A standard SPI or I2C DAC interface is required

Check before use

  • Verify external BJT voltage and current capability
  • Verify loop supply headroom at maximum output current
  • Validate SWIF protocol timing and isolation circuitry
