AMPLIFIER
„ DESCRIPTION
The UTC MC34119 is a low power audio amplifier IC intended 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 is not required. Open
loop gain is 80dB, and the closed loop gain is set with two external
resistors. The Mute pin permits powering down and/or muting the
input signal.
„ FEATURES
* Wide operating supply voltage: V_CC=2V~16V
* Low quiescent supply current (I_CC=2.7mA, typ)
* Medium power output over 250mW at V_CC=6V,
R_L=32Ω, THD＜10%
* Load impedance range (8Ω~100Ω)
* Low total harmonic distortion (0.5% typ)
* Mute function (I_CC=65μA, typ)
* Minimum number of external parts required
