LSI Computer Systems LS6501LP
The LS6501LP is a monolithic, CMOS Silicon Gate integrated circuit, designed for detecting motion from a PIR Sensor and initiating appropriate responses. The detailed description of the functional blocks is as follows: DIFFERENTIAL AMPLIFIER Each stage of the two stage Differential Amplifier can be set to have its own amplification and bandwidth. The two inputs to the first stage allow for single ended or differential connection to PIR Sensors.| Part No. | LS6501LP |

DESCRIPTION
: (See Figure 2) This stage can be biased anywhere in its dynamic range. The second stage is internally biased so that the Window Comparator’s lower and higher thresholds can be fixed relative to this bias. WINDOW COMPARATOR The Window Comparator provides noise filtering by enabling only those signals equal to or greater than a fixed threshold at the output of the Differential Amplifier to appear at the output of the Window Comparator.
