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.
Features
● Wide operating supply voltage (2~16V)
● Chip disable input to power down the IC
● Low quiescent current for battery powered
application
● Lower power down quiescent current
● Drives a wide range of speaker load (8~100Ω)
● Output power exceed 250mW with 32Ωspeaker
● Low total harmonic distortion
● Gain adjustable for voice band
● Requires few external components
