LS6505 - PIR SENSOR INTERFACE

Description

(See Figure 2) The LS6505 is a CMOS integrated circuit, designed for detecting motion from a PIR Sensor and initiating appropriate responses.

DIFFERENTIAL AMPLIFIER Each stage of the two stage Differential Amplifier can be set to have its own amplification and bandwidth.

Features

  • Direct Interface with PIR Sensor.
  • Two-Stage Differential Amplifier.
  • Amplifier Gain and Bandwidth externally controlled.
  • Window Comparator and Digital Filter limit Noise.
  • Triac Output Drive.
  • Programmable Output Duration Timer.
  • Selectable Dead Time.
  • Single or Dual Pulse Detection.
  • Timing derived from 50Hz/60Hz AC.
  • Motion Detection LED Indicator.
  • LS6505 (DIP), LS6505-S (SOIC)- See Figure 1.
