The MC34119 is a low power audio amplifier intergrated circuit intended
(primarily) for telephone applications, such as in speakerphones. It provides
differential speaker outputs to maximize output swing at low supply voltages
(2.0 V minimum). Coupling capacitors to the speaker are not required. Open
loop gain is 80 dB, and the closed loop gain is set with two external resistors.
A Chip Disable pin permits powering down and/or muting the input signal.
The MC34119 is available in standard 8–pin DIP, SOIC package, and
TSSOP package.

DESIGN GUIDELINES
Figure 1. Turn–On Time versus C1, C2 at Power–On
General
The MC34119 is a low power audio amplifier capable of
360
low voltage operation (V
= 2.0 V minimum) such as that
CC
encountered in line–powered speakerphones. The circuit
300
provides a differential output (V –V ) to the speaker to
O1 O2
maximize the available voltage swing at low voltages. The
differential gain is set by two external resistors. Pins FC1 and
FC2 allow controlling the amount of power supply and noise
rejection, as well as providing alternate inputs to the
amplifiers. The CD pin permits powering down the IC for
muting purposes and to conserve power.

closed loop gain is set by external resistor R and R . The
f
i
amplifier is unity gain stable, and has a unity gain frequency
of approximately 1.5 MHz. In order to adequately cover the
telephone voice band (300 Hz to 3400 Hz), a maximum
closed loop gain of 46 is recommended. Amplifier #2 is
internally set to a gain of – 1.0 (0 dB).
The outputs of both amplifiers are capable of sourcing and
sinking a peak current of 200 mA. The outputs can typically
swing to within ≈0.4 V above ground, and to within ≈1.3 V
Chip Disable
The Chip Disable (Pin 1) can be used to power down the
IC to conserve power, or for muting, or both. When at a Logic
“0” (0 V to 0.8 V), the MC34119 is enabled for normal
operation. When Pin 1 is at a Logic “1” (2.0 V to V
V), the
CC
IC is disabled. If Pin 1 is open, that is equivalent to a Logic
“0,” although good design practice dictates that an input
should never be left open. Input impedance at Pin 1 is a
nominal 90 kΩ. The power supply current (when disabled) is
shown in Figure 15.
Muting, defined as the change in differential gain from
normal operation to muted operation, is in excess of 70 dB.
The turn–off time of the audio output, from the application of
the CD signal, is <2.0 µs, and turn on–time is 12 ms–15 ms.

The output dc offset voltage (V –V ) is primarily a
function of the feedback resistor (R ), and secondarily due to

the amplifiers’ input offset voltages. The input offset voltage
of the two amplifiers will generally be similar for a particular
IC, and therefore nearly cancel each other at the outputs.

The output offset voltage, specified in the Electrical
Characteristics, is measured with the feedback resistor
shown in the Typical Application Circuit, and therefore takes
into account the bias current as well as internal offset
voltages of the amplifiers. The bias current is constant with
removing the signal from the speaker. If signals from other
sources are to be applied to the outputs (while disabled), they
must be within the range of V
and Ground.

Power Dissipation

Figures 8 to 10 indicate the device dissipation (within the
IC) for various combinations of V , R , and load power. The
maximum power which can safely be dissipated within the
MC34119 is found from the following equation:
CC
CC
L
FC1 and FC2
Power supply rejection is provided by the capacitors (C1
and C2 in the Typical Application Circuit) at FC1 and FC2. C2
is somewhat dominant at low frequencies, while C1 is
dominant at high frequencies, as shown in the graphs of
Figures 4 to 7. The required values of C1 and C2 depend on
the conditions of each application. A line powered
speakerphone, for example, will require more filtering than a
circuit powered by a well regulated power supply. The
amount of rejection is a function of the capacitors, and the
equivalent impedance looking into FC1 and FC2 (listed in the

In addition to providing filtering, C1 and C2 also affect the
turn–on time of the circuit at power–up, since the two

of each of the three curves is defined by the power level at
Layout Considerations
which 10% distortion occurs. The center flat portion of each
curve is defined by the maximum output current capability of
the MC34119. The right (descending) portion of each curve is
defined by the maximum internal power dissipation of the IC
at 25°C. At higher ambient temperatures, the maximum load
power must be reduced according to the above equations.
Operating the device beyond the current and junction
temperature limits will degrade long term reliability.
Normally a snubber is not needed at the output of the
MC34119, unlike many other audio amplifiers. However, the
PC board layout, stray capacitances, and the manner in
which the speaker wires are configured, may dictate
otherwise. Generally, the speaker wires should be twisted
tightly, and not more than a few inches in length.

MC34119 : Low Power Audio Amplifier
ADVANCED
The MC34119 is a low power audio amplifier
Page Contents
intergrated circuit intended (primarily) for telephone
applications, such as in speakerphones. It provides
differential speaker outputs to maximize output swing
at low supply voltages (2.0 V minimum). Coupling
capacitors to the speaker are not required. Open loop
gain is 80 dB, and the closed loop gain is set with two
external resistors. A Chip Disable pin permits
powering down and/or muting the input signal. The
MC34119 is available in standard 8–pin DIP, SOIC
package, and TSSOP package.
