1 / 15 page 1/15 TDA7296 February 2005 1 FEATURES ■ MULTIPOWER BCD TECHNOLOGY ■ VERY HIGH OPERATING VOLTAGE RANGE (±35V) ■ DMOS POWER STAGE ■ HIGH OUTPUT POWER (UP TO 60W MUSIC POWER) ■ MUTING/STAND-BY FUNCTIONS ■ NO SWITCH ON/OFF NOISE ■ NO BOUCHEROT CELLS ■ VERY LOW DISTORTION ■ VERY LOW NOISE ■ SHORT CIRCUIT PROTECTION ■ THERMAL SHUTDOWN 2 DESCRIPTION The TDA7296 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 high- est power into both 4 Ω and 8Ω loads even in pres- ence of poor supply regulation, with high Supply Voltage Rejection. The built in muting function with turn on delay sim- plifies the remote operation avoiding switching on- off noises. 70V - 60W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY Figure 2.
