Lm380 Audio Power Amplifier Circuit

The supply current to the ic varies in accordance with the input signal.

Lm380 audio power amplifier circuit.

The internal design of this ic can be fixed by designers like 34db. 0 13w vs 18v minimum gain is internally fixed at 34 db. Mini audio amplifier circuit. Peak current is high etc.

Lm380 1features description wide supply voltage range. Which use outside equipment adds least. The c6 can choose get many the value since 47uf to at 470uf which have a voice good bass. This is mini size power amplifier 2 watt otl that use ic lm380.

The output automatically self centers to one half the supply voltage. The output is short circuit proof with internal thermal limiting. The output automatically self centers to one half the supply voltage. Consequently there will be a similarly varying voltage drop across resistors r6 r7 r8 and r9 since these are in the supply lines to the op amp.

A unique input stage allows ground referenced input signals. A unique input stage allows ground referenced input signals. In order to hold system cost to a minimum gain is internally fixed at 34 db. The output is short circuit proof with internal thermal limiting.

10v 22v the lm380 is a power audio amplifier for consumer applications. The audio signal is applied to the non inverting input of power op amp ic1 tda2030 via socket k1 and capacitor c1. Be base readymade circuit for side sound work and the communication. In order to hold system cost to a low quiescent power drain.

The lm380 is a power audio amplifier for consumer applica tions. The lm380 ic is one kind of audio amplifier mainly used for power audio amplification. This ic includes a copper lead frame and features of this ic includes the range of supply is wide less distortion. In order to hold system cost to a minimum gain is internally fixed at 34 db.
