TDA7376PD 2 x 35 W power amplifier for car radio Features High output power capability: 2 x 40 W max./4 2 x 35 W/4 EIAJ 2 x 25 W/4 14.4 V, 1 kHz, 10 % 2 x 25 W/2 14.4 V, 1 kHz, 10 % PowerSO36 (Slug up) 2 driving Differential inputs Minimum external components count Description Internally fixed gain (26 dB) The TDA7376PD is a new technology dual bridge Mute function (CMOS compatible) audio amplifier in PowerSO36 package designed Automute at minimum supply voltage detection for car radio applications. Standby function Thanks to the fully complementary PNP/NPN output stage configuration the TDA7376PD No audible pop during mute and standby delivers a rail-to-rail voltage swing with no need of operations bootstrap capacitors. Clipping detector with programmable distortion threshold Differential input pairs, that will accept either single ended or differential input signals, Protections: guarantee high noise immunity making the device Short circuit (out to ground, out to supply suitable for both car radio and car boosters voltage, across the load) applications. Overrating chip temperature with soft The audio mute control, that attenuates the output thermal limiter signal of the audio amplifiers, suppresses pop Load dump voltage on - off transients and cuts any noises coming Fortuitous open ground from previous stages. The standby control, that Loudspeaker DC current de-biases the amplifiers, reduces the cost of the ESD power switch. The on-board programmable distortion detector allows compression facility whenever the amplifier is overdriven, so limiting the distortion at any levels inside the presettable range. Table 1.
