LOW POWER AUDIO
AMPLIFIER
DESCRIPTION
The UTC MC34119 is a low power audio amplifier
integrated
circuit,
intended
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.
