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
• Low Power–Down Quiescent Current (65 mA Typ)
• Drives a Wide Range of Speaker Loads (8.0 W and Up)
• Output Power Exceeds 250 mW with 32 W Speaker
• Low Total Harmonic Distortion (0.5% Typ)
• Gain Adjustable from <0 dB to >46 dB for Voice Band
• Requires Few External Components
