All that is left is a minimum of external components required for the user to have control over some functions. 1. LM4871 Audio Amplifier IC. Fig. It supports a 4-18V supply voltage range, allowing it to be used in many different audio applications. You probably know that LM317 IC is used as an adjustable voltage regulator, but did you know it can be used as an audio amplifier? Leistung an 4 Ohm … Where to use it? MERUS™ audio amplifier solutions ensure outstanding performance, maximum flexibility and highest reliability. It commonly used in class-AB audio amplifier and can drive upto 50W music power into a 4 ohm speaker. Finally I found one that sounds great, so I’m going to show you how to build it. Address the needs of any audio application with the industry’s broadest portfolio of speaker amplifiers (including Class-D, Class-D boosted, Class-AB and smart amps) ranging from 5 W to more than 50 W of output power and a range of topologies, performance and features. The circuit diagram of the audio amplifier is shown in Fig. Leistung an 4 Ohm und 2 x 250W max. Audio amplifier circuits can also be made using simple op-amps, but if you need higher volume that is loud enough for a room then this power audio amplifier is will be the best choice.
