Overview
LA4809M is a 2-channels power amplifier to drive the headphone with wide supply voltage range.
To minimize the effects of power supply, the regulator circuit for control of the output power is built-in to enable setting of the output power value adequate for the headphone amplifier (2 types of set value available). This product also has the standby function, and is suitable as a driver for wide-ranging headphone.

FEATUREs
• 2-channels power amplifier built-in (maximum output power value changeable according to the setting)
    Maximum output power A = 55mW Standard (Pin 10 : Open)
    Maximum output power B = 160mW Standard (Pin 10 : GND)
        *VCC = 12V, RL = 16Ω, THD = 10%
        *Change to another power value possible by adding the external parts
• Regulator built-in : Limited change of the output power value due to fluctuation of supply voltage High-Ripple rejection ratio
• Standby function (also used for voice muting) : Current drain at standby = 0.01μA Standard (VCC = 12V)
• Overheat protection circuit built-in
• Wide supply voltage range (differing according to the set value of maximum output power) : VCC = 3.6V to 17V

APPLICATIONs
    Headphone driver for TV and audio equipment
