  • Method and apparatus for circuit with low IC power dissipation and high dynamic range
    Patent number: 9065413
    Abstract: An apparatus comprises a selected volume detector that detects a selected output volume; an analog output signal amplifier; a digital volume amplifier; a boost gain control element coupled to the selected volume detector; the analog output signal amplifier; and the digital volume amplifier; wherein the boost gain control element is configured to: keep a gain of a path of the digital volume amplifier and the analog output signal amplifier substantially constant, wherein the boost gain control element can adjust both: a) a gain of the digital volume control; and b) a gain of the analog output signal amplifier; to keep the gain of the path of the digital volume amplifier and the analog output signal substantially constant and equal to the selected output volume.
