TDA7492P13TR

Overview

The TDA7492P13TR is a dual BTL Class-D audio amplifier manufactured by STMicroelectronics, designed for single-supply operation. It operates within a wide voltage range of 8 V to 26 V and delivers up to 25 W per channel at THD = 10% with a 20 V supply and 8 Ω load. The device features four selectable fixed gain settings: nominally 21.6 dB, 27.6 dB, 31.1 dB, and 33.6 dB. It utilizes a PowerSSO-EP-36 package with an exposed pad down (EPD) design, eliminating the need for external heatsinks due to high efficiency. Key electrical parameters include a minimum operating temperature of -40°C and a maximum of +85°C.

Feature Summary

• Dual BTL Class-D architecture supporting stereo output configurations
• Four selectable fixed gain settings for flexible system integration
• Exposed-pad-down (EPD) PowerSSO-36 package enabling heatsink-free thermal management
• Integrated protection mechanisms including short-circuit and thermal overload safeguards

Applications

• LCD televisions
• Computer monitors
• Audio systems requiring single-supply operation

Procurement Notes

Verify the specific suffix 'P13TR' against official STMicroelectronics documentation to confirm the tape-and-reel packaging configuration. Ensure that the selected gain setting matches the application requirements, as the device offers discrete fixed options rather than continuous adjustment. Confirm compliance with environmental standards such as RoHS through the manufacturer's current datasheet before finalizing procurement specifications.

Selection Notes

Select this component when designing audio circuits that require high efficiency and robust thermal performance without additional cooling hardware. The wide input voltage range supports various power supply architectures common in consumer electronics. Consider the available gain options during schematic design to ensure proper signal levels are achieved from the source. Verify that the load impedance aligns with the specified output power ratings to maintain reliability.

Part Context

This part belongs to the TDA7492 series of audio amplifiers, which are optimized for display applications like LCD TVs and monitors. The series emphasizes high efficiency and simplified thermal design through specialized packaging. The TDA7492P13TR variant specifically denotes the surface-mount version intended for automated assembly processes, maintaining the core performance characteristics of the broader family while adapting to modern manufacturing requirements.
