Lm380 Audio Power Amplifier Circuit

A unique input stage allows ground referenced input signals.

Lm380 audio power amplifier circuit.

Lm380 2 5w audio power amplifier check for samples. In order to hold system cost to a minimum gain is internally fixed at 34 db. Be base readymade circuit for side sound work and the communication. The output automatically self centers to one half the supply voltage.

The output is short circuit proof with internal thermal limiting. Peak current is high etc. Lm380 1features description wide supply voltage range. The c6 can choose get many the value since 47uf to at 470uf which have a voice good bass.

The audio signal is applied to the non inverting input of power op amp ic1 tda2030 via socket k1 and capacitor c1. Mini audio amplifier circuit. 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.

The lm380 is a power audio amplifier for consumer applica tions. 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. In order to hold system cost to a minimum gain is internally fixed at 34 db.

Additionally this ic offers high i p impedance. 0 13w vs 18v minimum gain is internally fixed at 34 db. A unique input stage allows ground referenced input signals. The lm380 ic is one kind of audio amplifier mainly used for power audio amplification.

The supply current to the ic varies in accordance with the input signal. The internal design of this ic can be fixed by designers like 34db. Which use outside equipment adds least. The output is short circuit proof with internal thermal limiting.
