Thule Audio's GND Management by Integrated Amplifier with RC - who can explain
There are two grounds: Analog GND and digital GND (D-GND)
The kind of creation I don't understand and I have never seen by others. At first look it shows like a symmetrical supply voltage about +/-5VDC. But there is only one voltage: +5Vdig. Because no additional secundary winding for independent creating of the +5Vdig is in use, this way was choiced from Anders Thule. The neg regulator drives a bidirectional diode (normally anti paralleling 1N4148) and creates 0V7DC refer to GND (A-GND). But the actually GND wire for the neg regulator goes here to +5Vdig !! What about this idea from Anders Thule? Who can give me a commonly circuit describtion ? Last edited by tiefbassuebertr; 10th February 2010 at 05:14 PM. |
