SSGSC34119
Elektronische Bauelemente Low Power Audio Amplifier
DESCRIPTION
The SGSC34119 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.
