NOTES:
1. The R9, R10, C9 network provides a 2.7V Peak-to-Peak AC signal input to Pin 5.
2. The C8, D1, Z1, C7, R7 components generate the DC Supply Voltage for the LS6501LP.
3. The R2, C2, R3, C3, R4, C4, R5, C5, R6, C6 components and the two on-chip Differential Amplifiers
set a nominal gain of 5,500 with bandpass filtering of 0.13Hz to 6Hz.
4. The value of R6 may have to be adjusted if the particular PIR sensor selected causes the input static voltage
at Pin 15 to be out of the input dynamic range. This is specified under Electrical Characteristics as 0V to 2.5V.
5. Sensitivity can be adjusted to a lower value by increasing the value of R2 or R4
or by decreasing the value of R3 or R5.
