TS34119

Low Power Audio Amplifier

1/12

Version: B13

SOP-8

General Description

The TS34119 is a low power audio amplifier, it 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 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.
