Overview
The TDA7492ETR is a Class-D audio amplifier manufactured by STMicroelectronics, housed in a 36-pin PowerSSO EP package with tape and reel packaging. It supports mono or stereo output configurations with a typical single supply voltage range of 9V to 24V, operating between 7V and 26V. The device delivers up to 110W into a 3-ohm load or 57W into a 6-ohm load. Key electrical parameters include a THD+N of 0.04% at 1W and an operating temperature range from -40°C to 85°C.
Feature Summary
- Class-D architecture providing high efficiency for speaker amplification
- Supports both mono and stereo output channel configurations
- Operates on a wide-range single power supply
- Low total harmonic distortion plus noise performance
Applications
- Speaker amplification systems
- Audio equipment requiring differential or single-ended outputs
Procurement Notes
Verify the specific suffix 'ETR' indicates tape and reel packaging when sourcing. Confirm the active status directly with the manufacturer or authorized distributors, as component availability can change. Ensure the PowerSSO EP package type matches your PCB footprint requirements before ordering.
Selection Notes
Select this component for applications requiring a single-supply Class-D solution with high power output capabilities. Consider the 36-pin PowerSSO EP package for thermal management needs without external heatsinks in some configurations. Verify that the required gain settings and protection features align with the system design specifications.
Part Context
This part belongs to the TDA7492 series of dual BTL Class-D audio amplifiers designed for LCD TVs, monitors, and home audio. The series offers high efficiency and various output power options depending on the load impedance and supply voltage. The ETR variant specifically denotes the tape and reel packaging format for automated assembly.
Replacement Considerations
Check for other TDA7492 variants such as TDA7492PE or TDA7492P13TR which may differ in packaging or specific electrical characteristics. Ensure any substitute maintains the same PowerSSO EP package and pinout compatibility.
