Lm380 Audio Amplifier Circuit

Lm380 1features description wide supply voltage range.

Lm380 audio amplifier circuit.

The circuit can be connected in four stages which include the following. The input stage in the above circuit is an emitter follower and it is composed of pnp transistors like q1 and q2. The working of the circuit is very straight forward as all the work is done by the lm386 ic itself. A great sounding lm386 audio amplifier.

The output automatically self centers to one half the supply voltage. A simple but efficient audio amplifier is designed using lm386 audio amplifier ic. Mini amplifier circuit diagram using lm380. A unique input stage allows ground referenced input signals.

Mini audio amplifier circuit. Normally we use 12 voltage for this amplifier circuit diagram. In the car also can use this circuit diagram. Be base readymade circuit for side sound work and the communication.

We get only 5 watts from this circuit diagram. The c6 can choose get many the value since 47uf to at 470uf which have a voice good bass. The simplicity of this circuit is made possible by the lm380 s minimal requirements for external components since it is already internally equipped with the necessary biasing compensation and gain circuits. If you need only vocal then you can use this circuit diagram.

When the system is powered on and proper audio input is given at the input the lm386 amplifier the input signal by a factor of 200 and drives the output speaker. Now that you ve seen the bare minimum of what it takes to make an audio amplifier with the lm386 lets build a higher fidelity version with an adjustable gain control. The circuit shown in figure 1 is a very simple audio power amplifier. In order to hold system cost to a minimum gain is internally fixed at 34 db.

But this sound is so clear and melody. The lm380n audio amp. I was a little intimidated by this ic the first time i looked at the datasheet because of all the ground connections. The output is short circuit proof with internal thermal limiting.

The lm380 is a power audio amplifier for consumer applica tions. Circuit description figure 1shows a simplified circuit schematic of the lm380. Emitter follower pnp emitter follower. The main component of this circuit is the lm380 audio amplifier.

I thought it was a little silly. It s run 9 voltage to 15 voltage. But after prototyping with this audio amp i don t think i ll ever go back to the lm386. 10v 22v the lm380 is a power audio amplifier for consumer.

This is mini size power amplifier 2 watt otl that use ic lm380. Which use outside equipment adds least.
