LOW POWER AUDIO AMPLIFIER

www.DataSheet4U.com UTC34119 DESCRIPTION LI NEAR I NTEGRATED CI RCUI T LOW POWER AUDIO AMPLIFIER The UTC34119 is a low power audio amplifier integrated circuit intended (primarily) for the telephone applications, such as in speakerphones. 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.
