The TS34119 is a low power audio amplifier from Texas Instruments, suitable for applications such as 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.
