The Salens AS083-SS1 is a low‑power CMOS PIR controller IC with built‑in amplifier, algorithm unit and adjustable timing for reliable motion detection.
The AS083-SS1 is a CMOS‑process PIR controller IC designed with mixed‑mode analog and digital circuitry for high stability and low power consumption. It incorporates a high‑precision algorithm unit that self‑adjusts to the environment, filters interference, and can detect human motion at distances of over twenty meters.
Key features include an internal reference voltage for the PIR sensor, built‑in operational amplifiers, a high‑precision crystal, and a programmable timing delay with 12 selectable steps. The chip is supplied in a compact SOP8 package and is suitable for applications such as automatic lighting, security alarms, door‑bell systems, digital cameras, and smart toys.
