Lm380 Audio Power Amplifier Circuit

In order to hold system cost to a minimum gain is internally fixed at 34 db.

Lm380 audio power amplifier circuit.

This is mini size power amplifier 2 watt otl that use ic lm380. The lm380 ic is one kind of audio amplifier mainly used for power audio amplification. Be base readymade circuit for side sound work and the communication. Lm380 2 5w audio power amplifier check for samples.

The lm380 is a power audio amplifier for consumer applica tions. 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. 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 low quiescent power drain.

A unique input stage allows ground referenced input signals. The audio signal is applied to the non inverting input of power op amp ic1 tda2030 via socket k1 and capacitor c1. In order to hold system cost to a minimum gain is internally fixed at 34 db. The output automatically self centers to one half the supply voltage.

A unique input stage allows ground referenced input signals. 0 13w vs 18v minimum gain is internally fixed at 34 db. Additionally this ic offers high i p impedance. Peak current is high etc.

The output automatically self centers to one half the supply voltage. The supply current to the ic varies in accordance with the input signal. The lm380 is a power audio amplifier for consumer applications. The c6 can choose get many the value since 47uf to at 470uf which have a voice good bass.

The output is short circuit proof with internal thermal limiting. The internal design of this ic can be fixed by designers like 34db. 10v 22v the lm380 is a power audio amplifier for consumer applications. Lm380 1features description wide supply voltage range.
