About: Myself Ramji Patel. A student of B -Tech Electronics and communication engineering in I.E.R.T. Prayagraj, Affiliated to Dr. A. P. J. Abdul Kalam Technical University, Lucknow. I like to design Digital & Analog…

INTRODUCTION:

In this Instructables I am going to make an audio power amplifier using LA4160 IC. LA4160 IC is an monolithic integrated circuit that contains pre amplifier, power amplifier and ALC (Automatic Level Control) circuit. In order to make an audio power amplifier, we can use the power Amplifier block of this IC to make an audio power amplifier.so Let's get started!
