Ist der peak bei 4,5V reproduzierbar?

Messung mit 400kHz, Peak scheint eine Eigenart der Drosseln zu sein, oder ein Seiteneffekt der Umschaltung der Modulation.

Zitat Soren:

Zitat:Hi Christian,

The "Hybrid" scheme is an attempt to combine the best of 1SPW and BD mode worlds. 1SPW is often very good with idle loss (battery power), but when the transition from 2N to 1N operation occurs (one output stuck at GND), it influences audio due to this nonlinear transition. Furthermore some applications will have CM ringing on the outputs. The hybrid scheme acts to keep the device in 1SPW as long as possible by increasing the output CM with increased modulation index, until it is at PVDD/2 (BD mode).

Best regards,
Søren

Ich weiss nicht, ob das zusammengehört.
