Lm380 Audio Power Amplifier Circuit

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

Lm380 audio power amplifier circuit.

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

Additionally this ic offers high i p impedance. The output is short circuit proof with internal thermal limiting. The lm380 is a power audio amplifier for consumer applications. The supply current to the ic varies in accordance with the input signal.

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. 10v 22v the lm380 is a power audio amplifier for consumer applications. The lm380 is a power audio amplifier for consumer applica tions. Which use outside equipment adds least.

Lm380 2 5w audio power amplifier check for samples. The internal design of this ic can be fixed by designers like 34db. 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.

Peak current is high etc. The audio signal is applied to the non inverting input of power op amp ic1 tda2030 via socket k1 and capacitor c1. The output automatically self centers to one half the supply voltage. In order to hold system cost to a low quiescent power drain.

Mini audio amplifier circuit. 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. This ic includes a copper lead frame and features of this ic includes the range of supply is wide less distortion.
