- Kinetis Rock 'n' Roll! 1kW Class-D Audio Amplifier
Kinetis Rock 'n' Roll! 1kW Class-D Audio Amplifier
Kinetis Rock 'n' Roll! 1kW Class-D Audio Amplifier
Kinetis Rock 'n' Roll! 1kW Class-D Audio Amplifier
Reference Solution being developed with Kinetis V (also can be done with a Kinetis K device) of a Class-D audio amplifier.
- 16-bit ADC sampling the audio input
- FlexTimer doing the PWM's for the Class-D amplifier
- DC/DC switched power supply with input of 12V and output of 130V to 180V (generates the power you need for making some good noise - 1kW) being controlled by the Kinetis MCU also.
- Capabiltiy of Audio processing/filtering using the Cortex-M4 DSP capabilities.
Solution originally designed for cost-effective Automotive aftermarket sound systems. But can be adapted for implementing other audio amplifier applications also in the consumer space!
Can you thing of cool applications/markets that this solution can be also quickly adapted?
Soon, plan to make the reference solution design files available in the community. Stay tunned.
Cheers!
