TDA7376B 2 x 35 W Power amplifier for car radio Datasheet - production data Protections: short circuit (out to ground, out to supply voltage, across the load) overrating chip temperature with soft thermal limiter load dump voltage fortuitous open ground loudspeaker dc current 0 03 ESD Multiwatt15 Description The TDA7376B is a new technology dual bridge audio amplifier in Multiwatt 15 package designed for car radio applications. Thanks to the fully Features complementary PNP/NPN output stage High output power capability: configuration the TDA7376B delivers a rail-to-rail 2 x 40 W max./ 4 voltage swing with no need of bootstrap capacitors. 2 x 35 W/4 EIAJ 2 x 25 W/4 (14.4V, 1kHz, 10 %) Differential input pairs, that will accept either 2 x 25 W/ 2 (14.4V, 1kHz, 10 %) single ended or differential input signals, guarantee high noise immunity making the device 2 driving suitable for both car radio and car boosters Differential inputs applications. Minimum external components count The audio mute control, that attenuates the output Internally fixed gain (26 db) signal of the audio amplifiers, suppresses pop On - Off transients and cuts any noises coming Mute function (cmos compatible) from previous stages. The standby control, that Automute at minimum supply voltage detection de-biases the amplifiers, reduces the cost of the Standby function power switch. The on-board programmable distortion detector allows compression facility No audible pop during mute and standby whenever the amplifier is over driven, so limiting operations the distortion at any levels inside the presettable Clipping detector with programmable distortion range. threshold Table 1.
