TDA2052 60W Hi-Fi AUDIO POWER AMPLIFIER WITH MUTE / STAND-BY SUPPLY VOLTAGE RANGE UP TO ±25V SPLIT SUPPLY OPERATION HIGH OUTPUT POWER (UP TO 60W MUSIC POWER) LOW DISTORTION MUTE/STAND-BY FUNCTION NO SWITCH ON/OFF NOISE AC SHORT CIRCUIT PROTECTION THERMAL SHUTDOWN ESD PROTECTION DESCRIPTION The TDA2052 is a monolithic integrated circuit in Heptawatt package, intended for use as audio class AB amplifier in TV or Hi-Fi field application. Thanks to the wide voltage range and to the high out current capability it's able to supply the highTEST AND APPLICATION CIRCUIT Heptawatt ORDERING NUMBER: TDA2052 est power into both 4 and 8 loads even in presence of poor supply regulation. The built in Muting/Stand-by function simplifies the remote operations avoiding also switching onoff noises.
