Overview
The TDA7491HV13TR is a dual BTL Class-D audio amplifier from STMicroelectronics, designed for LCD TVs and monitors. It operates on a wide-range single supply of 5V to 18V, delivering 20W continuous output power per channel at 8Ω load with 10% THD at 18V. The device features high efficiency of 90%, four selectable fixed gain settings (20dB, 26dB, 30dB, 32dB), and differential inputs to minimize common-mode noise. It includes protection against short circuits and thermal overload, along with standby and mute functions.
Feature Summary
- Dual BTL Class-D architecture providing stereo output without requiring a separate heatsink due to high efficiency and exposed-pad packages.
- Filterless operation capability reduces external component count while maintaining audio performance.
- Integrated protection mechanisms include short-circuit protection and thermal overload protection for reliable operation.
Applications
- LCD televisions
- Computer monitors
- Audio systems requiring single-supply operation
Procurement Notes
Verify the specific suffix 'HV' indicates the PowerSSO-36 EPD package variant compatible with the TDA7491P family. Confirm that the ordering code matches the required exposure pad configuration for your PCB layout. Ensure the voltage supply range aligns with the 5V to 18V specification before integration.
Selection Notes
Select this component when a dual-channel solution is needed for display audio applications. It serves as a pin-to-pin compatible alternative to the TDA7491P and TDA7491LP models. Consider its filterless design if minimizing passive components is a priority for the circuit board space.
Part Context
This part belongs to the TDA7491 series of Class-D amplifiers by STMicroelectronics. It shares functional compatibility with the TDA7491P and TDA7491LP variants within the same product family, offering similar protection features and gain settings tailored for consumer electronics displays.
Replacement Considerations
The TDA7491P13TR and TDA7491LP13TR are pin-to-pin compatible substitutes within the same series. Verify package orientation and thermal requirements when swapping between HV, P, and LP variants.
