How to build a mini Audio Amplifier using IC LA 4510

Introduction

You can come across thousands of audio amplifier circuits on the web. Some with built around transistors alone, but some are with hybrid types - both transistors and Integrated circuits. There are audio amplifier circuits built with ICs alone. Many circuits with different audio output capacities work on different voltages.  Here in this circuit design, the audio amplifier is built around a single IC i.e. LA 4510. It is a very unique and simple IC capable of delivering adequate sound output for small general-purpose amplifiers.   

The specialty of the circuit design

IC LA 4510 is a versatile tiny SIL IC that works like an audio amplifier for small compact audio systems. Broadly it is used in the following gadgets widely. 

AM/FM Radio receivers

Small personal music systems

Tape recorders

CD players

Headphone amplifiers

Any general-purpose audio amplifiers

Salient features of the circuit design

Low cost

Simple design with very few components

Needs only 3V DC operation

Hence dry cells can be used as power consumption is low

Extremely portable gadgets can be used

Delivers 200mW audio power output with 8 ohms speaker

No other transistor or diode is used along with the IC
