It's a stereo amplifier, nothing's special about this project, it's partly based on reference design.
- All SMD components are 1206 sized regardless of their advantages over audio designs.
- Input capacitor should be chosen something over 470uF/6V but the footprint I used has lead size 5mm.
- The coil I used in LPF part of circuit is from CoilCraft, its product code is JA4575-BL.
- Etc.
I'm not an EE, or had any educations about this topic, it's just my hobby project I consider to use in my future audio projects.
- Make room for bigger decoupling caps and include multi pads for variable input capacitor types (5mm, 8mm, etc.) to the design.
- (Optional) Add a boost converter to the circuit.
- Use more common coils in LPF.
- LPF in front of AVDD may be needed, if it's not just include 0R resistors in place.
- Make optimizations at audio input part.
- (Optional) Make it perfect 👊.
Never tested but I'm confident. 💥
