UTC - MC34119 LOW POWER AUDIO AMPLIFIER
| Previous | 9 / 182 | Next |
LOW POWER AUDIO 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: VCC=2V~16V
* Low quiescent supply current (ICC=2.7mA, typ)
* Medium power output over 250mW at VCC=6V, RL=32Ω, THD£¼10%
* Load impedance range (8Ω~100Ω) * Low total harmonic distortion (0.5% typ)
* Mute function (ICC=65μA, typ)
* Minimum number of external parts required
