IL34119 Low Power Audio Amplifier

Pin 1 2 3 Symbol CD FC2 FC1 Description Chip Disable - Digital input. A Logic “0” (<0.8 V) sets normal operation. A Logic “1” (≥2.0 V) sets the power down mode. Input impedance is nominally 90 KΩ. A capacitor at this pin increases power supply rejection, and affects turn-on time. This pin can be lef.

TECHNICAL DATA Low Power Audio Amplifier 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 inp.
