LS6511 - PIR SENSOR INTERFACE

General Description

(See Figure 5) The LS6511 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.

Key Features

  • Direct Interface with PIR Sensor.
  • Two-Stage Differential Amplifier.
  • Amplifier Gain and Bandwidth externally controlled.
  • True and Complementary Output Drives.
  • Separate digital filters for processing positive and negative input signals.
  • Single Pulse/Dual Pulse/ Concurrent Pulse Detection.
  • Adjustable Output Pulse Width.
  • Optional 5V Shunt Regulator Output.
  • 50µA Typical Supply Current.
  • Undervoltage Detection.
