| Key benefits |
| Class D amplifiers offer some serious advantages as compared to class AB audio amplifiers: |
 |
Very high efficiency, rating of up to 90%. This translates simply into a much more powerful audio signal for the same power consumption used for an equivalent class AB circuit. Or conversely, much lower power consumption for any given audio volume. |
|
Class D topology also offers a simplified, filter-free circuit design, leading to a lower total component count for any given application. |
