LOW POWER AUDIO AMPLIFIERYD8602
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=32Ω, THD=10%;
*Load impedance range (8Ωto 100Ω);
*Low distortion;
*Mute function (Icc=65μA, typ.);
*Minimum number of external parts required.
