Smart Ultrasonic Sensor IC with Dual Interface

Smart Ultrasonic Sensor IC with Dual Interface

This device offers the best distance measurement performance in ultrasonic applications.
The integrated driver stage excites an ultrasonic transducer via a center-tap transformer.
An adjustable transducer damping circuit optimizes the short range. The device receives
the reflected signal and processes it for reliable obstacle recognition.
