The TDA7491MV13TR is a mono BTL Class-D audio amplifier 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, or 25W at 6Ω load with 10% THD at 16V. It features high efficiency of 90%, differential inputs, and filterless operation. The component is housed in a 36-pin PowerSSO EP package and supports four fixed gain settings: 20dB, 26dB, 30dB, and 32dB.
Verify the specific suffix 'MV13TR' against official STMicroelectronics documentation to confirm it denotes the tape-and-reel packaging variant of the TDA7491MV. Ensure the ordering part number matches the exact pinout and thermal pad configuration required for your PCB layout. Cross-reference the datasheet revision date to confirm compliance with current environmental standards such as RoHS and REACH requirements.
Select this component when a single-channel high-efficiency solution is required without external heat sinks. It is suitable for designs needing filterless topology to save space. Verify that the system voltage stays within the 5V to 18V range. Confirm that the chosen fixed gain setting aligns with the input signal level to prevent clipping or insufficient volume.
This part belongs to the TDA7491 family of Class-D audio amplifiers. It is pin-to-pin compatible with the TDA7491P, TDA7491LP, and TDA7491HV for the left channel configuration. While the TDA7491P offers dual stereo output, the MV variant provides a dedicated mono output optimized for specific single-speaker applications within the same product line.
The TDA7491P, TDA7491LP, and TDA7491HV are officially documented as pin-to-pin compatible alternatives for the left channel. Note that these replacements may offer different channel configurations (dual vs. mono) or slight variations in output power ratings under identical conditions.
