POWER AMPLIFIER FOR HEADPHONE STEREOS—YD7000
DESCRIPTION
The YD7000 is a low power audio amplifier integrated circuit for headphone. It provides differential speaker outputs to maximize output swing at low supply voltages.
FEATURES
*Low current consumption. *16Ω load drive capability. *Excellent reduced voltage characteristics. *Excellent power supply ripple rejection. *Minimum number of external pares required (no input capacitor, feedback capacitor required). *Applicable to radio sets because of high voltage gain. *Less harmonic interference in radio band. *On-chip power switch function, muting function.
