UTC MC34119 LINEAR INTEGRATED CIRCUIT

LOW POWER AUDIO

AMPLIFIER

DESCRIPTION

The UTC MC34119 is a low power audio amplifier

integrated circuit, 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.

A chips disable 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 output power( Po=250mW at Vcc=6V,

RL=32ohm, THD=10%)

*Load impedance range(8 to 100ohm)

*Low distortion

*Mute function(Icc=65µA, typ)

*Minimum number of external parts required
