com ISSUED DATE :2005/02/18 REVISED DATE : G P 3 4 11 9 Description LOW POWER AUDIO AMPLIFIER The GP34119 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.
0V 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.
Features Wide Operating Supply Voltage Range (2.
0V to 16V), Allows Telephone Line Powered Applications Low Quiescent Supply Current ...
