Your personal data will be provided to ST local affiliates and distributors in countries located in the European Union and outside of the European Union. In this tutorial, I’ll show you how to build a great sounding audio amplifier with the LM386 Low Voltage Audio Power Amplifier.I built about a dozen different audio amplifier circuits with the LM386 but most of them had way too much noise, popping, and other interference. Power Amplifier ICs Power amplifiers provide amplification of a signal for use in transmitting radio frequency signals through an antenna within a defined frequency range. The audio circuit should be duplicated, but the power supply assists to the two channels without problems. The LM series originated with integrated circuits made by National Semiconductor. The portfolio addresses a broad range of premium class D applications. High performing Class-D amplifiers for a range of audio applications 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. 2×60 Watts audio amplifier – This is a high quality audio amplifier designed using LM4780 IC, which is capable of delivering 60 watts RMS power per channel into 8 0hms speakers. The circuits are easy to assemble, with a minimum of external parts needed to complete an amplifier. The LM4780 has very low total harmonic distortion and has a power supply rejection ration (PSRR) of 85 dB. Then someone may think that a 20-watt amplifier per channel is low power when in fact it is not because here we talk about real power or RMS. These amplifiers are used for high-quality sound applications. This might be an integrated amplifier, but it really is more like a separate pre- and power amplifier in a single box rather than a compromised electrical design. Feedback capacitor high pass roll off Fc = 1 / (2 pi R1 C1). Elcircuit.com is an electronics blog committed to review the latest updates about the development of the electronics technology. The amplifier is built around a single integrated circuit (IC), the TDA2050V which is produced by STMicroelectronics. sir. Class A is the most linear type of audio amp, but it has low efficiency.
