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.

DESCRIPTION
This pin can be used to power down the IC to converse power, or for muting, or
both. When at a logic “LOW” (less than 0.8V), the IC is enabled for normal
operation. When at a logic “HIGH” (2V to Vcc), the IC is disabled. If Mute is open,
that is equivalent to a logic “LOW”.
A capacitor at this pin increase power supply rejection, and affects turn-on time.
This pin can be left open if the capacitor at pin 3 is sufficient.
Analog Ground for the amplifiers. A 1μF capacitor at this pin ( with a 5μF
capacitor at pin 2) provides 52dB( typ) of power supply rejection. Turn-on time of
the circuit is affected by the capacitor on this pin. This pin can be used as an
alternative input.
Amplifier input. The input capacitor and resistor set low frequency roll-off and
input impedance. The feedback resistor is connected between this pin and output
1.
Amplifier output 1. The DC level is about (Vcc~0.7V)/2.
DC supply voltage is applied to this pin(Vcc=2~16V).
Ground pin.
Amplifier output 2. This signal is equal in amplitude, but 180°out of phase with
that output 1, the DC level is about (Vcc~0.7V)/2.
