We used TAS2521 EVM board to test the chip.
We have one issue when the volume goes high:
The register in 0x2D page on page 1 (Speaker Amplifier Control 1) goes automaticaly to value 0x00 spk driver is powered down .
What could be the cause, how can we correct this issue.
This is happened with this differents speaker, at different level.
Thank for your
Ok,
We are using 4 ohms speakers , adding 1 ohms in serial on speaker lines seems to fixe the issue.
Do you have some recommandation to add RC filter or LC on the speaker line for 4 ohms speakers to protect the amplifier?
The documentation speak about HP over current register but not Speaker over current ?
Thank for help
