LOW POWER AUDIO AMPLIFIERYD34119A
DESCRIPTION
The YD34119A is a low power audio amplifier integrated circuit intended (primarily) for the telephone
applications, such as in speakerphones.
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.
