It provides differential speaker outputs to maximize output swing at low supply voltages. Coupling Capacitor to the speaker are not required. Open loop gain is 80dB, and the closed loop gain is set with two external resistors. A chips Disable pin permits powering down and/or muting the input signal. FEATURES Wide operating supply voltage: Vcc=2~16V Low quiescent supply current(Icc=2.7mA,typical) Medium output power Po=250mW at Vcc=6V,RL=32ohm ,Thd=10% Load Impedance range(8 ohms to 100 ohm) Low distortion Mute function(Icc=65µA, typical) *Minimum number of external parts required.
