Low Power Audio Amplifier
TECHNICAL DATA
IL34119
The IL34119 is a low power audio amplifier integrated 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 volts 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 IL34119 is available in a standard 8
pin DIP or a surface mount package.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND(VIN or
VOUT)VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
