MC34119DR2 Datasheet

Audio Amplifiers


The MC34119DR2 is a low power audio amplifier integrated circuit intended for telephone applications, such as in speakerphones. It 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. MC34119DR2 Features &bull; Wide Operating Supply Voltage Range (2.0 V to 16 V), Allows Telephone Line Powered Applications&bull; Low Quiescent Supply Current (2.7 mA Typ) for Battery Powered Applications&bull; Chip Disable Input to Power Down the IC&bull; Low Power--Down Quiescent Current (65 &mu;A Typ)&bull; Drives a Wide Range of Speaker Loads (8.0 &Omega; and Up)&bull; Output Power Exceeds 250 mW with 32 &Omega; Speaker&bull; Low Total Harmonic Distortion (0.5% Typ)&bull; Gain Adjustable from <0 dB to >46 dB for Voice Band&bull; Requires Few External Components&bull; Pb-Free Packaging Designated by Suffix Code EF
