MC34119

Order this document by MC34119/D Low Power Audio Amplifier The MC34119 is a low power audio amplifier intergrated 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 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. The MC34119 is available in standard 8–pin DIP, SOIC package, and TSSOP package. Wide Operating Supply Voltage Range (2.0 V to 16 V), Allows Telephone Line Powered Applications Low Quiescent Supply Current (2.7 mA Typ) for Battery Powered Applications Chip Disable Input to Power Down the IC MC34119 LOW POWER AUDIO AMPLIFIER SEMICONDUCTOR TECHNICAL DATA 8 1 Low Power–Down Quiescent Current (65 µA Typ) Drives a Wide Range of Speaker Loads (8.0 Ω and Up) Output Power Exceeds 250 mW with 32 Ω Speaker Low Total Harmonic Distortion (0.5% Typ) Gain Adjustable from <0 dB to >46 dB for Voice Band Requires Few External Components 8 P SUFFIX PLASTIC PACKAGE CASE 626 1 MAXIMUM RATINGS Rating Supply Voltage Maximum Output Current at VO1, VO2 Maximum Voltage @ Vin, FC1, FC2, CD Applied Output Voltage to VO1, VO2 when disabled Junction Temperature NOTE: ESD data available upon request.
