Why Choose a Class-D Amplifier Like TDA7498E?
Class-D amplifiers use pulse-width modulation (PWM) to reduce power loss. This allows them to:
- Run cooler
- Use smaller heatsinks
- Deliver higher power output with lower power consumption
Compared to Class-AB amps, Class-D gives more sound with less energy.
Designing with TDA7498E
Designing a board with the TDA7498E is simple if you follow proper layout and cooling methods. Tips include:
- Use large ground planes for better stability
- Add heatsinks or metal enclosures to manage heat
- Pair with good quality power supplies for best performance
- Add proper LC filters to clean up PWM switching noise
