AS8412 - HIGH PERFORMANCE AUTOMOTIVE SONAR INTRUSION

Description

The AS8412 is a signal processing IC designed to implement reliable, high-performance sonar intrusion detectors.

It generates short 40 kHz bursts to feed an ultrasonic transducer.

The resulting sonar waves are reflected on the vehicle interior and the echoes are received by another transducer.

Features

  • True sonar/pulse-echo operation Wide dynamic range Programmable sensitivity levels Self-adaptive to vehicle interiors Self-adaptive to temperature and environmental changes High sensitivity to intrusion Immunity to false alarms Detection of sabotage attempts Compatible with standard 40 kHz ultrasonic transducers No adj.
