TDA7387 ST Audio Amplifier | 25FLEXIWATT（垂直） | 4x45W, 4-Channel

Product Overview

The TDA7387 is a class AB audio power amplifier in the 25FLEXIWATT (vertical) package, designed for high-quality car radio applications. It integrates four independent amplifier channels capable of delivering 45W each into 4Ω loads (max. power) or 28W each into 4Ω loads (continuous power) at 14.4V supply voltage with low distortion. The device features a fully complementary PNP/NPN output stage, a low-noise input stage, and protection against short circuits, thermal overload, and load dump voltage surges. Its compact vertical package enables efficient heat dissipation and space-saving PCB layout.
