TDA8954J ,2 x 210W Class-D Power Amplifier, 42.5V, High Efficiency

The TDA8954J is a highly efficient Class D power amplifier IC designed to deliver up to 2 x 210 W in stereo configuration with a 4 Ω load or 1 x 420 W in mono bridge-tied load (BTL) configuration with an 8 Ω load. It combines the superior efficiency of Class D amplification (>93%) with low power dissipation, making it ideal for high-power audio applications such as home theater systems, public address systems, and subwoofers. This IC operates over a wide supply voltage range from 12.5 V to 42.5 V, making it flexible for various audio setups. The TDA8954J includes multiple protection features, such as Thermal Fold Back (TFB), Over Current Protection (OCP), and Over Temperature Protection (OTP), ensuring safe operation and longevity.

The IC supports stereo single-ended (SE) and mono BTL configurations, providing flexibility for different speaker setups. With a low quiescent current and pop noise-free start-up, the TDA8954J ensures minimal power consumption during standby and offers superior audio quality without distortion. Its high efficiency, combined with robust protection mechanisms, makes it the perfect choice for modern audio amplification needs.
