My Light Diagram

This Simple 50W Electronic Amplifier Circuit Diagram project is an IC amplifier module from ST Microelectronics, the TDA7294. It is intended for use as a top quality audio class AB amplifier in hi-fi applications. It's low noise and distortion, wide bandwidth and nice output current capability, enabling it to supply high power in to both four ohm and 8 ohm lots. It's both short circuit and thermal protection. With the addition of a handful of parts and an appropriate power supply, this module will deliver over 50W RMS in to four or 8 ohms-with < 0.1% Total Harmonic Distortion (THD) and < 0.1% Inter-modulation Distortion (IMD). It is also suitable as a replacement power amp stage, or upgrade for plenty of existing amplifiers of between 30W-50W, provided they have an appropriate dual supply, & most do. The Specifications of the electronic amplifier project there are: D.C. Input : 35V Output power : > 50W RMS, 4-8 ohm load. Gain : 24 dB (30dB modification) Input sens...

Power amplifier Class-B is the most popular operating modes, and possibly more than 99% of the current series of power amplifier designed and manufactered are of this class. Defining the Class-B is the amount of bias voltage that causes conduction of both output devices to overlap with the current and thus produce the minimum amount possible crossover distrosi. This Class-B power amplifier performance : Power Output________________________50W RL Impedance_______________________8R Distortion__________________________Below 0.0006% at 1 kHz and 50W/8R Slew rate___________________________Approximately 35V/us Noise______________________________-91dBu at the output EIN_______________________________-117dBu (referred to input) Frequency response__________________+0, -0.5dB over 20Hz-20kHz Part List : Resistor R1,R8____________________________10K R2,R3,R13________________________100R R4_______________________________150R R5,R10___________________________1K R6,R7____________________________68R ...
