Sensor _ Smoke Detector Controller

With the E520.30, Elmos presents a fully programmable platform for an optical smoke detector with a bus interface. The analog, addressable integrated circuit needs just a minimum of external components for setting up the complete system. The E520.30 is a high current driver for the transmitter LED and a high impedance input to voltage conversion of the receiver diode.
