Preliminary
LINEAR INTEGRATED CIRCUIT
PIR INFRARED REMOTE CONTROL CIRCUIT
DESCRIPTION
The M3000 is a passive infra-red controller using analog mixing digital design technique and is manufactured by CMOS process.
The M3000 needs only few external components in application circuit.
It can be applied in controller of light, electric switching, burglar alarm, and so on.
FEATURES
* Low Power CMOS Technology * CMOS High Input Impedance Operational Amplifiers * Bi-Directional Level Detector / Excellent noise Immunity * Built-in Power up Disable & Output Pulse Control Logic * Dual Mode : Retriggerable & Non-Retriggerable
