Quad amplifier 40W

This circuit provides a total of four speakers 4 ohms and 40W at 12v powered. It is therefore ideal for use in the car. Total harmonic distortion is rather high, about 10% at full power. But with half the power requirements (20W) is less than 2%. Anyway it is not intended to have a high performance system in the car. With the integrated audio TDA8571J designed for automotive applications, this 40w amplifier circuit can expand the sound of the car radio or connect a portable MP3 player in it. Internally, the chip has eight operational amplifier set on the bridge, allowing each speaker terminal being energized. Dont connect the negative terminal of the mass of the speaker, because they will produce a […]

36 Watt Audio Power Amplifier based on TDA1562Q

The amplifier based on the class H from Philips audio amplifier IC, it can deliver 36W RMS and 70W power music, all from the supply voltage of 13.8V.  This amplifier can provide 36W RMS continuous into 4 ohm load when using a 13.8Vsupply. However, it is able to deliver 70W output power signal (music) in the dynamic condition. As we can see from the drawings and  schematic diagrams, this powerful amplifier uses only few part. As we can see from the schematic drawings and diagrams, this powerful amplifier uses only few part. It is built on a PCB size 104mm x 39mm, but even though its size may be simple, but not with his ability. This amplifier also has excellent noise and distortion. An important components of the circuit is an integrated circuit TDA1562Q ”monolithic integrated Bridge Tied Load (BTL) class H power amplifier with high efficiency.” Form in17-pin package “DIL-bent-SIL” plastic and not only designed for use in car audio amplifier and […]
