Smart Ultrasonic Sensor IC with Dual Interface | E524.37

This device offers the best distance measurement performance in ultrasonic applications. The integrated driver stage excites an ultrasonic transducer via a center-tap transformer. The device receives the reflected signal and processes it for reliable obstacle recognition. This outstanding performance is achieved by an analog frontend with a highly sensitive, lownoise amplifier and an advanced digital signal processing. In particular, the signal processing with its numerous functions (dynamic gain, noise suppression,...) allows very short, long and accurate distance measurements. Multiple interfaces support a variety of different applications and architectures, e.g. standard LIN systems with a higher-level control unit or systems without control unit and local bus communication. In addition, the embedded 32-bit microcontroller with pre-defined functions and customer re-programmable memory offers maximum flexibility.
