Lm380 Audio Amplifier Circuit

Which use outside equipment adds least.

Lm380 audio amplifier circuit.

The output is short circuit proof with internal thermal limiting. I thought it was a little silly. In order to hold system cost to a minimum gain is internally fixed at 34 db. Mini amplifier circuit diagram using lm380.

The main component of this circuit is the lm380 audio amplifier. The circuit can be connected in four stages which include the following. A simple but efficient audio amplifier is designed using lm386 audio amplifier ic. Lm380 1features description wide supply voltage range.

A great sounding lm386 audio amplifier. It s run 9 voltage to 15 voltage. Normally we use 12 voltage for this amplifier circuit diagram. Be base readymade circuit for side sound work and the communication.

Most of the component values in this circuit aren t critical. 10v 22v the lm380 is a power audio amplifier for consumer. 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. But this sound is so clear and melody.

But after prototyping with this audio amp i don t think i ll ever go back to the lm386. The circuit shown in figure 1 is a very simple audio power amplifier. 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. The output automatically self centers to one half the supply voltage.

Emitter follower pnp emitter follower. In the car also can use this circuit diagram. The input stage in the above circuit is an emitter follower and it is composed of pnp transistors like q1 and q2. We get only 5 watts from this circuit diagram.

I was a little intimidated by this ic the first time i looked at the datasheet because of all the ground connections. The working of the circuit is very straight forward as all the work is done by the lm386 ic itself. This is a simple audio amplifier using lm380 ic. If you need only vocal then you can use this circuit diagram.

The lm380n audio amp. Circuit description figure 1shows a simplified circuit schematic of the lm380. A unique input stage allows ground referenced input signals. This paper describes the circuit operation of the lm380 its power handling capability methods of volume and tone con trol distortion and various application circuits such as a bridge amplifier a power supply splitter and a high input impedance audio amplifier.

This is mini size power amplifier 2 watt otl that use ic lm380. Mini audio amplifier circuit.
