| YOUDA INTEGRATED CIRCUIT YD8602 LOW POWER AUDIO AMPLIFIER--YD8602 DESCRIPTION The YD8602 is the audio power amplifier available for low voltage. It supplies differential outputs for maximizing output swing at low voltages. FEATURES *Wide operating supply voltage: Vcc=2~6V; *Low quiescent supply current (Icc=2.7mA, typ.); *Medium output power Po=250mW at Vcc=6V, RL=32, THD=10%; *Load impedance range (8to 100); *Low distortion; *Mute function (Icc=65A, typ.); *Minimum number of external parts required.
