Car Power Amplifier based TDA1562

Car Power Amplifier based TDA1562
Audio amplifier is built with the main component of Philips TDA1562 IC. The TDA1562 is a monolithic integrated 70 W/4 W. Bridge-Tied Load (BTL) class-H high efficiency power amplifier in a 17 lead DIL-bent-SIL plastic power package. Its essence is that to a certain value output (approx. 20 watts) amplifier operates in the mode B. If the output power increases further, included a clever scheme to increase the voltage output stage and thus enables the amplifier to swing to

60 / 120 watts Power Amplifier LM4780

60 / 120 watts Power Amplifier LM4780
Operating power amplifier integrated circuit LM4780 from National Semiconductor . What is special? Well, first of all - it is very low harmonic distortion. Typically, manufacturers indicate the maximum power of its regular genius crafts at THD 10%. At the same chip, the CG at the maximum specified power is only 0.5%! (more…)

240W Class D Audio Amplifier based TDA8924

240W Class D Audio Amplifier based TDA8924
Power amplifier operates in class D power amplifier is powerful enough produces a total output power 240 W (120 W each channel). Much power is generated by a chip made ​​by Philips TDA8924. Reference Data : Supply voltage : ±12V ...± 30V Supply current absence of a signal : 100mA Output power (max) in stereo : 120W in mono : 240W Efficiency : 90% (more…)

1.4W Stereo Power Amplifier Circuit based TDA8552

1.4W Stereo Power Amplifier Circuit based TDA8552
A few more words on the chip. This is a bridge amplifier class AB integrated into the protection against overheating, short circuit protected outputs, suppression of inrush current when you turn on and off the amplifier. The only difference - a little more power output - 1.4 watts per channel. But nevertheless, it also does not require a heat sink and can be used anywhere. (more…)
