    TDA7294 is a monolithic integrated circuit in Multiwatt15 package, with high output power (up to 100W) 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 4W and 8W loads even in presence of poor supply regulation, with high Supply Voltage Rejection.

    1. Boy will the younger guys be able to use “loose transistors” on a TAGSTRIP ? Like we more seniors built our amps when we were learning the trade? Remember bending a chassis with a garden fork as a brake? Huge power? 10(ten) watts with OC 35 transistors and those thermionic tubes (valves)? The first power i.c. the Sinclair IC10?

      What should I do with standby?

    3. Hi guys, I did the 100watt TDA7294 it sounds so great, I want to try the TDA7294 250watts bridged amp, so how can I get the PCB layout. Thanks in advance.

    4. It works!

    5. where should the standby pin connected????

    6. is it work on car battery or plz provide 250watts bridged amp PCB layout plz plz i am just intrusted in sound system it is my hobby or plz provide some more circuit 60 watt or 80 watt output work with car battery

        Preet hi! The highest power that a car battery amplifier can give is about 20 watts depending on conditions like battery charge and so on. To get all the power you will have to use an inverter that boost the voltage to what you need
