Diodes D1 and D2 together with capacitors C1 and C2 form a voltage multiplier. This is required because the integrated circuit operates with a minimum supply voltage of 12 V, while the door bell installation provides 8 V.
The input voltage supplied to the circuit must be alternating current.
Technical Specifications:
Integrated circuit: LS1240A.
Supply type: AC voltage.
Minimum IC supply voltage: 12 V (via voltage multiplier).
Nominal input voltage: 8 V AC.
Sound frequency: determined by R1 and C3.
PCB dimensions: 42 x 24 mm.
