LSI Computer Systems LS6511N
The LS6511N, LS6512 and LS6513 are CMOS integrated circuits designed for detecting motion from a PIR Sensor and initiating appropriate responses. The two inputs to the first stage allow for single-ended or differential connection to PIR Sensors. This stage can be biased anywhere in its dynamic range.| Part No. | LS6511N |

APPLICATIONS
: Security system intrusion detection, automatic doors, motion triggered events such as remote animal photography, etc.DESCRIPTION
(See Figure 5) DIFFERENTIAL AMPLIFIER Each stage of the two stage Differential Amplifier can be set to have its own amplification and bandwidth. The second stage is internally biased so that the Window Comparator’s lower and higher thresholds can be fixed relative to this bias. Signal levels as low as 100µV can be detected.
