The device builds the core for a robust and easy-to-handle distance measurement system, while offering flexibility for customer applications.

A driver unit stimulates the ultrasonic transducer via a centertapped transformer.... read more


  • Drives ultrasonic transducer via center-tapped transformer
  • Excellent short & long range performance due to:
    - Wide signal gain range / Sensitivity time control /
       Static and automatic thresholds /
       Near-field threshold /Echo peak detection /
       Fast time constant algorithm
  • Advanced IO protocol with configurable measurement profiles
  • IC and transducer diagnosis information
  • E524.08: 2-wire Interface
  • E524.09: 3-wire Interface
