My cause of construction of this project was to develop a compact design for a stereo amplifier can be integrated by a wrong (but the sound quality conscious!) Living student at a university or a college dormitory. audio amplifier 50W circuit The amplifier feeds a pair of speakers with two LM3876 amplifier integrated circuits (50 watts [...]
LM3886 68W Power Amplifier Circuit Diagram LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 468W Power Amplifier with LM3886 circuit load and 38W into 868W Power Amplifier with LM3886 circuit with 0.1% THD+N from 20Hz-20kHz. Features: Maximum Output Power : 68W RMS – 108W Peak THD [...]
Circuit Description There are many instances where a simple and reliable power amplifier is needed – rear and centre channel speakers for surround-sound, beefing up the PC speakers, low powered tweeter amplifier, etc. For those who want to build their own ‘Gainclone’ amplifier, this will certainly do the job This project (unlike most of the [...]
Dancing Leds Schematic Diagram Device purpose: The basic circuit illuminates up to ten LEDs in sequence, following the rhythm of music or speech picked-up by a small microphone. The expanded version can drive up to ten strips, formed by up to five LEDs each, at 9V supply. Circuit operation: IC1A amplifies about 100 times the [...]
