TS34119
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.
