SGM4810

SGM4810 Dual 158mW Headphone Amplifier with Active High Shutdown Mode GENERAL DESCRIPTION The SGM4810 is a dual audio power amplifier capable of delivering 158mW per channel of continuous average power with typically 0.1% distortion (THD+N) 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 components and can operate from a single 2.5V to 5.5V power supply. SGM4810 features an externally controlled, active-high, micro-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. FEATURES  Active-High Shutdown Mode  158mW into 16Ω Load from 5V Power Supply at THD+N = 0.1% (Typical, per Channel)  87mW into 32Ω Load from 5V Power Supply at THD+N = 0.1% (Typical, per Channel)  Unity Gain Stable  2.5V to 5.5V Operation  Shutdown Pin is Compatible with 1.8V Log...
