SGM4915 Dual 145m W Headphone Amplifier with Active Low Shutdown Mode GENERAL DESCRIPTION The SGM4915 is a dual audio power amplifier capable of delivering 145m W per channel of continuous average power with less than 0.1% distortion（THD） when it drives a 16Ω speaker from a 5.0V power supply. It is designed to maximize audio performance in portable applications such as mobile phone. The portable application requires audio power amplifier has minimum of external ponents and can operate from a single 2.5V to 5.5V power supply. SGM4915 Features an externally controlled, active-low, micropower consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. Features - Active-Low Shutdown Mode - 145m W into 16Ω Load from 5V Power Supply at THD+N = 0.1% Typical (per Channel) - 85m W into 32Ω Load from 5V Power Supply at THD+N = 0.1% Typical (per Channel) - Unity Gain Stable - Shutdown Current: 0.02µA (TYP) - 2.5V to 5.5V Operation -...
