This audio amplifier is designed for car radios each channel of the TDA7386 can develop 49 W at 15.2 volts with a load of 4 ohms with very high distortion and saturation levels.

Having decided to build an ultra-compact design, using a spare LM4780 seemed like an obvious plan. Having said that, I might choose a different IC if I didn't already have one to hand. The LM4780 contains two LM3886 dies (reference) giving 60 watts per channel, which is rather more than required this application. National Semiconductor make an enormous range of IC's with differing power levels and configurations, and there are plenty of possible candidates for this application - after all, we only need a few watts as this amplifier will principally be driving small speakers on the computer desk.

This is a basic design with a single LM3875TF chip per side, and one shared toroidal transformer. I will be making two of these amplifiers simultaneously but with a few critical component differences. One is based on standard components, and one on premium components. There was a lot of deliberation on the type of transformer to get, particularly the secondary voltages. The concern here is the target load as, generally speaking, the higher the voltage, the less suited it is to drive low impedance loads (4ohms). I settled on 20 volt secondaries which I think is a good compromise, feeling that 18v is perhaps a little too low and 22v a little too high to get the max with a 4 ohm load whilst minimising output loss if using 8 ohms. The ability to run stable at 4 ohms is paramount to me to keep it open to different applications, and output wattage is relatively unimportant for this design.
