The TDA7388 is a four-channel power audio amplifier in an integrated circuit form, designed for automotive applications and high-performance audio systems. It provides 4x45W output into 4Ω loads with low distortion and high fidelity, operates at a 14.4V supply voltage, and features built-in protections against overheating, short circuits, and overvoltage. The Multiwatt15 package makes it easy to mount on a heatsink, while the internal mute and standby management allows flexible operation control. It is ideal for car amplifiers, DIY audio projects, and multichannel systems with power and quality requirements.
