Mini Power amplifier in figure below is series of
amplifiers made with LM386 IC. Power amplifier LM386 IC chip is designed as a
monolithic power amplifier with low power and low power consumption. Power
amplifier CIRCUIT LM386 can be made as a power amplifier with a gain of 20 to
200 times depending on the configuration of the series. Power amplifier circuit
using LM386 amplifier IC power in General is a device that requires the
amplifier audio with small loudspeakers installed on the device.
Mini power
amplifier circuit LM386 is often applied on a radio device or toy that uses
small loudspeakers. A series of mini power amplifier with LM386 IC is a simple,
complete set of and list of components can be seen directly on the picture the following
mini power amplifier. Mini Amplifier Power Circuit LM386
Mini power amplifier circuit using LM386 IC above
can be operated with low voltage from 5 to 12 volts DC. With a simple
configuration as shown in the image above, the mini power amplifier circuit
LM386 ICS were able to provide input voltage gain by 20 times. Mini power
amplifier circuit above is one type of power amplifier mini type OTL (Output
Transformer Less) with a power of 0.5 watt. Power amplifier above can drive a
load (loud speakers) 8 Ohm with low power consumption. Potentiometer on the
mini power amplifier circuit LM386 above serves to adjust the volume of the
audio signal that is amplified by the mini power amplifier LM386.
