Input buffers for Class D amp

Dr.H · 17th May 2011, 04:24 PM

It seems that Class D amps suffer from a low input impedance (at least the ICEPOWER modules I have do, typically around 8k).

Any actual experience of good input buffers? I thought of BUF634, AD815 or a discrete JFET based unit...

This thread should give you some ideas.
