Overview
The TDA7491MV is a mono BTL Class-D audio amplifier IC manufactured by STMicroelectronics, designed for LCD TVs and monitors. It operates on a single power supply ranging from 5V to 18V. The device delivers 20W continuous output power at 8Ω load with 10% THD at 18V, and 25W at 6Ω load with 10% THD at 16V. It features high efficiency of approximately 90%, differential inputs, and four selectable fixed gain settings (20dB, 26dB, 30dB, 32dB). The component utilizes a PowerSSO-36 EPD package and supports filterless operation.
Feature Summary
- Filterless operation reduces external component count
- Exposed-pad-down package eliminates need for separate heatsink
- Differential inputs minimize common-mode noise
- Externally synchronizable for multi-amplifier systems
Applications
- LCD televisions
- Computer monitors
- Audio systems requiring high efficiency
Procurement Notes
Verify the specific suffix 'MV' against official STMicroelectronics documentation to confirm it denotes the mono configuration, as pinouts may differ from stereo variants like the TDA7491P or TDA7491HV. Ensure compatibility with the target PCB footprint, specifically the PowerSSO-36 exposed pad design, before finalizing procurement decisions.
Selection Notes
Select this component when a single-channel high-power solution is required for display applications. It serves as a direct replacement for the left channel of stereo amplifiers like the TDA7491P or TDA7491HV due to pin-to-pin compatibility. Consider its wide voltage range and thermal performance if space constraints prevent the use of additional cooling hardware.
Part Context
The TDA7491MV belongs to the TDA7491 family of D-class audio amplifiers. It shares architectural similarities with the TDA7491P, TDA7491LP, and TDA7491HV models but is configured for mono output. This family is characterized by high efficiency and integrated protection mechanisms, targeting cost-sensitive consumer electronics markets.
Replacement Considerations
The TDA7491MV is pin-to-pin compatible with the left channel of the TDA7491P, TDA7491LP, and TDA7491HV. When replacing a stereo amplifier with this mono unit, verify that the application requires only a single channel output.
