This design has been known at www.diyaudio.com and elsewhere and it has been bescribed thouroughly in couple of articles in The Audio Amateur and also in other magazines, like EDN. The design presented below is a developed/altered version (not necessarily better) and not identical to the one in the articles nor to the pcb from Audio Express. Some of the changes has Andrew L Weekes done and some have I done.

Interesting features

  1. Extremely low noise.
  2. Very low output impedance in the audioband.
  3. Small.
  4. Easy to change voltage, also to negative voltage.
  5. Well-known and well-tested in serious applications.
