General Description
The TS34119 is a low power audio amplifier, it integrated circuit intended (primarily) for telephone applicationsd 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
● 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
