The LM386 is an efficient digital amplifier power stage for driving speakers up to 3-5W in mono.
The advanced oscillator/PLL circuit employs multiple switching frequency options to avoid AM interferences.
The LM386 is fully protected against faults with short-circuit protection and thermal protection as well as over-voltage, under-voltage and DC protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions.
It can be used to directly drive small power speakers, suitable for microphone head amplifier Practical application: Deaf hearing aid: Board connected to the microphone head, power supply, headphones is a good effect of hearing loss of deaf
