Product Summary

The mc34119dr2 is a low power audio amplifier integrated circuit intended for telephone applications, such as in speakerphones. The mc34119dr2 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.
