Part Number: TAS2557

Hi Experts,

Our customer is using our TAS2557 and wants to know what's the issue or sound will happen, if the Vsense pins are disconnected or broken in real use case, can you help to check?

Thanks a lot!

    Hi Jacky,

    Would the device be running a speaker protection algorithm and playing audio? If sense pins are disconnected while the device is running algorithm that would not be good. The device would loss the feedback from the speaker thus could become out of control as there is not an actual reference for processing.
    Is this just for a safety check? I assume that customer wants to know what would happen if there is an accident and sense pins are disconnected, am I right?

    Best regards,
