It embeds 4 audio channels able to deliver a maximum power of 50 W each, it can drive loads as low as 2 W and operate from 6 to 18 V without popping or interruption. circuit diagram of high power audio amplifier 7-Now again join the 5th pin of the IC with the +ve side of 220 micro farad, the -ve side of the pin should be attached with the A of the 100 ohm variable resistor.The B pin of the variable resistor should be connected to the GND pin (4th pin of IC).This will become the volume controller. These amplifiers are used for high-quality sound applications. MERUS™ audio amplifier solutions ensure outstanding performance, maximum flexibility and highest reliability. It also has high gain and fast slew rate. List of PWM Amplifiers; Sánchez Moreno, Sergio (June 2005). 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. Consider that modern browsers: So why not taking the opportunity to update your browser and see this site correctly? The design uses innovative design techniques to achieve ultra-high power-supply rejection across the audio signal band while, at the same time, delivering a high-current Rail-to-Rail output drive capability. China High Power Amplifier wholesale - Select 2021 high quality High Power Amplifier products in best price from certified Chinese Amplifier manufacturers, Audio Amplifier suppliers, wholesalers and factory on Made-in-China.com You can re-use the validation code to subscribe to another product or application. or on the first circuit diagram (updated), I read your blog that's very nice. The STA540 contains four single-ended, class-AB audio amplifiers assembled in a Multiwatt15 package. Power amp ICs such as the LM3886 and TDA7293 are popular, and for good reasons.
