Headphone Stereos
Description
This is a bipolar IC designed for headphone stereos.
It provides functions such as automatic volume limiter
control, bass boost, standby, headphone driver and
others.
Features
• Low quiescent current (3.2mA at 2.4V Vcc )
• Thermal shutdown circuitry at 120°C
• Headphone driver (30mW at 2.4V Vcc for 16Ω load)
• Bass boost function (9dB)
• Standby function
• Wide operating voltage (1.8 to 5V)
• Automatic volume limiter control (100mVrms)
• Uses SOP 16 pin package
