SGM4809 - Dual 158mW Headphone Amplifier

Description

The SGM4809 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.

Features

  • an externally controlled, active-low, micro-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.

SGM4809 Dual 158mW Headphone Amplifier with Active Low Shutdown Mode GENERAL DESCRIPTION The SGM4809 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. SGM4809 features an externally controlled, active-low, micro-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. FEATURES  Active-Low Shutdown Mode  158mW into 16Ω Load from 5V Power Supply at THD+N = 0.
