4 / 25 page PRELIMINARY Page 4 of 25 Running mode: In running mode the output is triggered by the comparator. An offset cancellation feedback loop is formed by the A/D converter, dsp and offset cancellation D/A converter. In running mode switching always occurs at zero-crossing. It is only affected by the (small) remaining offset of the comparator and by the remaining propagation delay time of the signal path, mainly determined by the noise-shaping filter. Nevertheless signals below a defined threshold are not detected to avoid unwanted parasitic switching. Figure 3: Startup of the device At transition from startup-mode to running mode switching timing is moving from low-accuracy to high accuracy zero-crossing. startup-mode running-mode offset peak detection offset= (max + min) / 2 offset correction |
