The TDA7454 is a quad bridge audio amplifier designed for car radio applications, featuring a Flexiwatt 25 package. It delivers a maximum output power of 4 x 35W at 4 ohms under typical conditions, with a supply voltage range of 8V to 18V. The amplifier operates in both conventional Class AB mode and a high-efficiency mode, which significantly reduces thermal management requirements by dissipating less power compared to traditional Class AB amplifiers. Key features include low external component count, no need for bootstrap capacitors, and internally fixed gain of 26dB. The device also includes protection mechanisms against output short circuits, thermal overload, and load dump conditions. With a total harmonic distortion (THD) of 0.03% at 1W to 10W output, it provides high audio fidelity. The TDA7454 is RoHS compliant and suitable for automotive applications, making it a viable choice for engineers looking for a reliable audio amplification solution.
