com YOUDA INTEGRATED CIRCUIT YD7000 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.
