TDA7376B Description

The TDA7376B is a new technology dual bridge audio amplifier that comes in a Multiwatt 15 package. It was developed specifically for use in applications related to automobile radios. There is no requirement for bootstrap capacitors because the TDA7376B has a completely complementary PNP/NPN output stage architecture. This allows the device to deliver a rail-to-rail voltage swing. Differential input pairs, which will accept either single ended or differential input signals, offer strong noise immunity, making the device appropriate for use in applications relating to vehicle radios and car boosters.

The audio mute control, which reduces the volume of the signal output by the audio amplifiers, eliminates any pops and crackles that may have been produced by earlier stages and attenuates any transients that may occur. The cost of the power switch is brought down thanks to the standby control, which removes the bias from the amplifiers. The on-board programmable distortion detector enables compression capability if the amplifier is being over powered, so limiting the amount of distortion at any level that is within the range of levels that may be programmed.

Conclusion

For the most part, the TDA7376B is a high-performance dual bridge audio amplifier made for vehicle radio and automobile booster applications. It has a differential input pair that can take either single-ended or differential input signals and a completely complementary PNP/NPN output stage arrangement that provides a rail-to-rail voltage swing without bootstrap capacitors. The amplifier’s audio mute and standby features cancel out noise from earlier stages and mitigate “pop” while turning the amp on and off. The TDA7376B is a distortion limiter and compressor with a customizable clipping detection and distortion detector. Because it complies with RoHS regulations and achieves Automotive Electronics Council (AEC) Q100 certification, it can be used in vehicles. The amplifier is housed in a Multiwatt-15 package suitable for through-hole mounting, has a maximum output power of 37 watts, and can work from a supply voltage range of 9 volts to 15 volts.
