TS34119 Datasheet | Taiwan Semiconductor

Low Power Audio Amplifier .. Supply Voltage Range 2 V to 16V Gain Adjustable Range 0dB ~ 46dB Output Power 400mW @Vcc=12V, RL=100Ω 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. The TS34119 is offered in SOP-8 and DIP-8 package. Features —...
