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<10%
* Load impedance range (8Ω~100Ω)
* Low total harmonic distortion (0.5% typ)
* Mute function (ICC=65μA, typ)
* Minimum number of external parts required

PIN NAME
DESCRIPTION
This pin can be used to power down the IC to converse power, or for muting, or both. When
Mute
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”.
Ripple
A capacitor at this pin increase power supply rejection, and affects turn-on time. This pin
Rejection 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)
Input(+) 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
Input(-)
impedance. The feedback resistor is connected between this pin and output 1.
Output 1 Amplifier output 1. The DC level is about (VCC~0.7V)/2.
VCC
DC supply voltage is applied to this pin (VCC=2~16V).
GND
Ground pin.
Amplifier output 2. This signal is equal in amplitude, but 180°out of phase with that output 1,
Output 2
the DC level is about (Vcc~0.7V)/2.
