The LM380 is a power audio amplifier for consumer applications. In order to hold system cost to a minimum, gain is internally fixed at 34 dB. A unique input stage allows ground referenced input signals. The output automatically self-centers to one-half the supply voltage. Which amplifier provides twice output swing as that of LM380 amplifier? 9.
The Simplest Audio Amplifier Circuit Diagram

The amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. You can also make a 5W mono amplifier out of it. (Check out the TEA2025 datasheet for more information on that) On the input side, you should use a dual potentiometer. A dual potmeter allows you to connect both the left and right channels on one potentiometer.

amplifiers. On a single ended amplifiers the load are connected between an amplifier output and ground (GND). Bridged amplifiers work basically as follows: a single input signal is applied to the amplifier. Internal to the amp, the input signal is split into two signals. One is identical to the original, and the second is inverted (sometimes called
