    SS output question

    Is this even possible? This is supposedly from the manufacturer....

    The TDA7294 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications (Home Stereo, self powered loudspeakers, Topclass TV). Thanks to the wide voltage range and to the high out current capability it is able to supply the highest power into both 4Ω and 8Ω loads even in presence of poor supply regulation, with high Supply Voltage Rejection."

    I don't think they are saying that it can deliver the same power into 4 and 8 ohm. I think it is saying that it is low loss, so it will deliver the maximum power possible into whatever load you have. If you look at this datasheet ( on page 6 and look at Figures 3 and 5 you see that for a given rail voltage the power is higher for 4 ohm than 8 ohm.

    I see. They could have certainly worded it better. Thanks.
