TDA7492P13TR
Overview
The TDA7492P is a dual BTL class-D audio amplifier designed for high-efficiency sound reproduction in space-constrained applications. It operates across a wide supply voltage range of 8V to 26V and can deliver up to 25W per channel into 8-ohm loads. The device features integrated protection circuitry and four selectable gain settings to simplify system design.
Why Choose This Part
The high efficiency of the Class D architecture eliminates the need for large external heatsinks, significantly reducing PCB footprint. Integrated short-circuit and thermal overload protection ensure robust operation in consumer environments, while the differential inputs provide superior common-mode noise rejection.
Applications
Key Specifications
Getting Started
Engineers should focus on the PCB layout of the PowerSSO-36 package, ensuring the exposed thermal pad is properly soldered to a large ground plane for heat dissipation. Four gain levels (21.6 dB to 33.6 dB) can be configured via the GAIN0 and GAIN1 pins to match input source levels. Consider using the STEVAL-CCA044V1 evaluation board for rapid prototyping and performance verification.
