SL34119
Low Power Audio Amplifier
The SL34119 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.
0 volts 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 SL34119 is available in a standard 8 pin DIP or a surface mount package.
