STMicroelectronics 2-Channel Audio Power Amplifier Class D Surface Mount 80W PowerSSO 36-Pin TDA7498LTR

The STMicroelectronics TDA7498LTR is a high-efficiency 2-channel Class D audio power amplifier designed to deliver 80W output power. Housed in a compact 36-pin PowerSSO surface mount package, it is engineered for efficient power conversion, minimizing heat dissipation and reducing the need for large heatsinks. Operating over a wide voltage range from 14V to 36V, this amplifier provides flexibility for various power supply configurations. Its thermal tolerance allows operation up to 150°C, making it reliable for demanding use cases.

This amplifier supports both filtered and filterless operation modes, allowing designers to optimize system architecture according to application needs. An externally synchronizable clock feature enables precise synchronization with other audio components, enhancing audio fidelity. The amplifier's 400kHz gain bandwidth product ensures quality amplification with minimal distortion.

Measuring 10mm in length and width, and 2.15mm in height, the compact PowerSSO package simplifies integration into printed circuit boards, saving space in compact audio equipment. The device includes 2 output channels, suitable for stereo applications such as home audio, multimedia speaker systems, and embedded electronics.

STMicroelectronics’ TDA7498LTR is ideal for industrial, consumer electronics, and professional audio applications requiring efficient amplification with a small PCB footprint and robust thermal performance. Its Class D architecture is suited for energy-efficient, high-performance audio amplification, making it a preferred choice for designers targeting power-sensitive and space-constrained environments.
