General Description
The TS34119 is a low power audio amplifier, it integrated circuit intended (primarily) for telephone applications錛?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 80dB, 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 TS34119 is offered in SOP-8 and DIP-8 package.
