Datasheet for the TDA7294, a well-known high-power audio amplifier IC commonly found in hi-fi amplifiers, active speakers and DIY amplifier builds, supplied as a 1.13 MB PDF. It lists pin functions, supply voltage limits, standby and mute behaviour, typical application circuits and thermal data. Repair technicians use it to check correct supply rails, verify mute and standby pin voltages, and choose suitable replacement parts around the chip. Because counterfeit parts are common, compare markings and measured behaviour against the specifications given.
