2 x 210 W audio power amplifier Class-D

General description:
The TDA8954 is a stereo or mono high-efficiency Class D audio power amplifier in a  single IC featuring low power dissipation. It is designed to deliver up to 2 × 210 W into a 4 Ω load in a stereo Single-Ended (SE) application, or 1 × 420 W into an 8 Ω load in a mono Bridge-Tied Load (BTL) application. It combines the benefits of Class D efficiency (≈93 % into a 4 Ω load) with audiophile sound quality comparable to that associated with Class AB amplification. The amplifier operates over a wide supply voltage range from ±12.5 V to ±42.5 V and  features low quiescent current consumption. The TDA8954 is supplied with two diagnostic pins for monitoring the status of Thermal  Fold Back (TFB), Over Current Protection (OCP) and other protection circuits.

80W Operational Amplifier

General Description:
The LM12 is a power op amp capable of driving g25V at g10A while operating from g30V supplies. The monolithic IC can deliver 80W of sine wave power into a 4X load with 0.01% distortion.

The PA05 is a high voltage MOSFET power operational amplifier that extends the performance limits of power amplifier  in slew rate and power bandwidth, while maintaining high current and power dissipation ratings. The PA05 is a highly flexible amplifier. The shutdown control feature allows the output stage to be turned off for standby operation or load protection during fault conditions. Boost voltage inputs allow the small signal portion of the amplifier to operate at a higher voltage than the high current output stage. The amplifier is then biased to achieve close linear swings to the supply rails at high currents for extra efficient operation.

TDA8932B Class-D audio amplifier

General description
The TDA8932B is a high efficiency class-D amplifier with low power dissipation. The continuous time output power is 2 × 15 W in stereo half-bridge application (RL = 4 Ω) or 1 × 30 W in mono full-bridge application (RL = 8 Ω). Due to the low power dissipation the device can be used without any external heat sink when playing music. Due to the implementation of thermal foldback, even for high supply voltages and/or lower load impedances, the device continues to operate with considerable music output power without the need for an external heat sink. The device has two full-differential inputs driving two independent outputs. It can be used in a mono full-bridge configuration (BTL) or in a stereo half-bridge configuration (SE).
