Applications
The TDA7498MV is designed for high-power consumer audio applications including active subwoofers, home theater systems, and powered speaker enclosures requiring 100W mono output from a single-chip Class-D amplifier. Its high-efficiency switching architecture reduces power dissipation compared to Class-AB designs, allowing compact enclosures without large heatsinks in soundbar and mini-amplifier applications. The device also suits commercial sound reinforcement equipment and automotive aftermarket amplifier boards where a 37.6 dB gain stage with 22 kHz bandwidth is needed.

Frequently Asked Questions
What output power does the TDA7498MV deliver and under what supply conditions is it achieved?
The TDA7498MV delivers 100W nominal output power in mono Class-D mode, typically achieved with a supply voltage of 36V to 39V into a 4-ohm or 8-ohm speaker load. At lower supply voltages the output power scales quadratically; at 24V the output is approximately 45W into 4 ohms. The 37.6 dB gain stage amplifies a standard 1V line-level input to full rated power output.
How does the TDA7498MV's Class-D topology reduce thermal management requirements compared to Class-AB amplifiers at 100W?
Class-D amplifiers like the TDA7498MV achieve switching efficiencies above 90%, meaning that at 100W output the device dissipates less than 10W as heat in ideal conditions, compared to Class-AB which can dissipate 50W or more at the same output power level. The 36-pin PowerSSO exposed pad transfers this reduced thermal load efficiently to the PCB copper plane, often eliminating the need for a large external heatsink in subwoofer and speaker applications.
For a compact powered subwoofer design, how does the TDA7498MV's 36-pin PowerSSO package simplify PCB layout versus discrete MOSFET solutions?
The TDA7498MV integrates the full Class-D output bridge, gate drivers, and protection circuitry within a single 36-pin PowerSSO package, eliminating the need for 4 discrete MOSFETs, bootstrap capacitor drivers, and dead-time control logic that discrete solutions require. This consolidation reduces the PCB area by approximately 60% and lowers the component count by more than 20 parts, simplifying assembly and improving reliability for 100W subwoofer amplifier designs.
