AS8579-ASSM ams OSRAM, AS8579 Capacitive 24-Pin SSOP

The ams AS8579 series is a capacitive sensor that detects the change of capacity in different applications. The capacitive sensor measures the impedance that originates between a conducting surface and a human being. The IC captures the current of a metal object and applies algorithms to determine the capacitive and resistive information. The outcome information can be read through a SPI Interface that can be also used for IC configuration. This high precision performance sensor also supports a multitude of diagnostic features that meet standard functional safety requirements.

I/Q-Signal demodulation
Up to 10 independent measurement lines possible (10 SEN lines)
VAR&FIX_SEN function to avoid parasitic influences from cable and PCB
Designed according functional safety standard
Accurate capacitive measurement (separation of resis
