Hi TI,

Can you tell me the advantages and disadvantages of having an output voltage offset in the piezo position?

    Mason,

    Could you provide more information about your question?
    Do you need output offset? Have you used other drivers with offset at the output?

    When a load is connected in differential mode, like this case, any offset that is present at both sides of the connection (common-mode) is suppressed. If you need offset voltage in a differential load, you would need to induce the offset only on one side of the output pair. This is not common since most drivers are Class-D.
