Smart Direct Drive Ultrasonic Sensor IC with Dual Interface | E524.36

This device offers the best distance measurement performance in ultrasonic applications. The integrated driver stage directly excites a connected ultrasonic transducer and significantly reduces system cost and size, eliminating the need for a transformer and other external components. 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 (smart damping, 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 micro controller with pre-defined functions and customer re-programmable memory offers maximum flexibility
