    What is full power mode, 3/4 power mode, & 1/2 power mode?

    Hi All:

    When reading the datasheet of EL8108,
    http://www.intersil.com/content/dam/...n74/fn7417.pdf

    In page 4, typical performance curves,
    there are diagrams for full power mode, 3/4 power mode, & 1/2 power mode.


    What is the definition for xx power mode?

    Are they something related with the power efficiency , like different efficency for Class A, class D amplifiers?

    Re: What is full power mode, 3/4 power mode, & 1/2 power mode?

    The data sheet doesn't say but I would assume it refers to the amount of load placed on the output. This to some degree changes the internal feedback and hence gain/phase response of the amplifier. Full power I would guess is the measurement under maximim load, 1/2 power at half the maximum load and so on.

    You can't program the power and the amplifier can't change it's mode of operation so it must be a reference to how hard you are loading it.
