AVT794 A - acoustic amplifier with LM386 circuit. PCB board

Description

The presented project is a small-sized acoustic amplifier with a wide range of supply voltage. The system can operate at a supply voltage from 4VDC to 12VDC while maintaining low power consumption. Thanks to these properties, it is perfectly suitable for use in portable audio equipment, in children's toys, etc. One of the more popular integrated circuits - LM386 - was used to build the amplifier. Although it is not a new construction, it still enjoys interest, among others due to the relatively simple application system.
