LM386 Sound Detection Voice Sensor

AGOTADO!!

Descripción:

LM386 is an audio power amplifier with features of low power consumption, adjustable voltage gain, wide voltage power supply, less requirements on peripheral components and minimum total harmonic distortion. LM386 can be applied to the consumer products with low voltage requirement. To minimize the number of the peripheral components in used, the voltage gain should be set to 20. Connecting a resistant and a capacitor externally between the Pin1 and the Pin8, it is able to configure the voltage gain to any value within the range of 0-200.
