LS6522

Overview

The LS6522 is a dedicated sensor interface integrated circuit designed for passive infrared (PIR) motion detection applications. Manufactured by LSI Computer Systems, this component facilitates the conditioning and processing of signals from pyroelectric sensors. It is housed in a standard 16-pin Dual In-line Package (DIP), providing a robust solution for integrating motion sensing capabilities into security systems and automated control units.

Feature Summary

• Specialized interface circuitry tailored for PIR sensor signal processing
• Designed to enhance detection reliability in motion sensing applications

Applications

• Passive infrared motion detectors
• Security system alarm sensors
• Automated lighting control interfaces

Procurement Notes

Verify the specific package variant, such as LS6522-S, against project requirements. Confirm manufacturer authenticity through official LSI/CSI channels or authorized distributors. Ensure compatibility with existing PCB layouts and signal conditioning circuits before finalizing procurement decisions.

Selection Notes

Select the LS6522 when a dedicated interface for PIR sensors is required rather than general-purpose amplifiers. Consider the 16-DIP form factor for through-hole mounting needs. Evaluate if the specific signal processing characteristics align with the target sensor's output profile for optimal system performance.

Part Context

LSI Computer Systems specializes in custom mixed-signal integrated circuits. The LS6522 represents their expertise in sensor interface solutions, distinct from their programmable delay timers like the LS7211 series. This part serves niche applications requiring reliable motion detection signal conditioning.
