This 30W 60W audio amplifier is based on TDA7296 integrated audio amplifier.
The 30W 60W audio amplifier based on TDA7296 audio power amplifier ic from this diagram is very a simple power amplifier that can be used on many audio applications.
The TDA7296 30W 60W audio amplifier is provided with both stand-by and mute functions independently driven by two CMOS logic compatible input pins and optimized to avoid any kind of uncontrolled audible transient at the output.
This 30W 60W audio amplifier circuit is a class AB amplifier which can be used in Hi-Fi applications (Home Stereo, self powered loudspeakers, Topclass TV).
The maximum output power obtained with TDA7296 amplifier integrated circuit is around 60 watts .
Thanks to the wide voltage range and to the high out current capability it is able to supply the highest power into 4 and 8 ohms loads impedance.
The maximum power 60 watts is obtained with a power supply around VS = ± 29V on 8 ohms load impedance ; VS = ± 24V on 6 ohms load impedance ; VS = ± 22V on 4 ohms load impedance .
The maximum power 60 Watts delivered from this audio IC is obtained with 10% total harmonic distortions .
Using a power supply around VS = ± 24V on 8 ohms load impedance ; VS = ± 21V on 6 ohms load impedance ; VS = ± 18V on 4 ohms load impedance the maximum power delivered by amplifier is 30W but the total harmonic distortion is around 0.5% .
Main features of this amplifier are : high output power , high operating voltage 30V , muting and stand-by functions , thermal shutdown and short circuit protections .
