Lm380 Audio Amplifier Circuit Diagram

10v 22v the lm380 is a power audio amplifier for consumer.

Lm380 audio amplifier circuit diagram.

The internal circuits of both ics are almost same. Both the ics are able to deliver output power around 2w to 2 5 watt. Be base readymade circuit for side sound work and the communication. If you need only vocal then you can use this circuit diagram.

Mini amplifier circuit diagram using lm380. Emitter follower pnp emitter follower. Which use outside equipment adds least. The circuit is using lm380n version which is a 14 pin dip package ic with good features like it can be operated on a wide range.

It s run 9 voltage to 15 voltage. Mini audio amplifier circuit. Lm380 1features description wide supply voltage range. The circuit can be connected in four stages which include the following.

This is mini size power amplifier 2 watt otl that use ic lm380. The lm380 2 watt audio amplifier circuit shown here is an easy to build circuit using only few external parts and able deliver 2w to 2 5 watt output only on 10v dc. Lm380n 8 audio amplifier circuit ic is an another 8 pin dip version of lm380n audio amplifier ic which is available in 14 pin dip package. We get only 5 watts from this circuit diagram.

This is a simple audio amplifier using lm380 ic. Normally we use 12 voltage for this amplifier circuit diagram. The input stage in the above circuit is an emitter follower and it is composed of pnp transistors like q1 and q2.
